Mount handling is often unique in Linux. Let's ensure that the common
parts remain in mount.go, while Linux speific parts are within a linux
file.

Cgroups do not exist on Darwin, so use an empty implementation for
resourcecontrol for the time being. In the process, ensure that the
utilized cgroup handling (ie, isSystemdCgroup) is kept in general file,
since we use this to help assess/constrain the container spec we pass to
the guest.

With `disable_netns=true`, we should never scan the sandbox netns which

In TestHandleHugepages it will do a mount operation with different pagesizes,
but some systems only support 2M pagesize, test for a 1g pagesize will fail.
This commit try to fix by only mount pagesizes under `/sys/kernel/mm/hugepages`, which are
supported to mount by the OS.

Several tests utilize linux'isms like Mounts, bindmounts, vsock etc.
Let's ensure that these are still tested on Linux, but that we also skip
these tests when on other operating systems (Darwin). This commit just
moves tests; there shouldn't be any functional test changes. While the
tests still won't be runnable on Darwin/other hosts yet, this is a necessary
step forward.

This is needed in order to have Moby / Docker working properly with
Cloud Hypervisor, as Moby / Docker relies on hotplugging a network
device to the VM as a preStartHook.

THe only bit needed for having the vmAddNetPutRequest() capable of
dealing with hotplugs, instead of only coldplugs, is making sure it
doesn't error out in case a `200` response is returned.
The 200 response means:
"""
The new device was successfully added to the VM instance.

With nydus not being its own pkg, it is challenging to implement cleanly
in a virtcontainers package that isn't necesarily Linux-only. The
existing code utilizes network namespace code in order to ensure nydus
is launched in the host netns. This is very Linux specific - so let's
make sure we only carry this out in a linux specific file.
In the Darwin case, to allow for compilation at least, let's add a stub
for doNetNS. Ideally the nydus and vc code can be refactored /
decoupled.

Substitution in the yq install script doesn't like zsh, and additionally
the version of yq we're using doesn't have a darwin/arm64 build so grab
the amd64 version and let rosetta work its magic.
Additionally swap to abspath from readlink -m for the printing of what binaries
to install, as the -m flag doesn't exist on the BSD variant, and this
should be the same behavior.
