David Gibson 1ab72518b3 agent: Fix to parsing of /proc/self/mountinfo ...

get_mounts() parses /proc/self/mountinfo in order to get the mountpoints
for various cgroup filesystems.  One of the entries in mountinfo is the
"device" for each filesystem, but for virtual filesystems like /proc, /sys
and cgroups, the device entry is arbitrary.  Depending on the exact rootfs
setup, it can end up being "-".

This breaks get_mounts() because it uses " - " as a separator.  There
really is a " - " separator in mountinfo, but in this case the device entry
shows up as a second one.  Fix this, by changing a split to a splitn, which
will effectively only consider the first " - " in the line.

While we're there, make the warning message more useful, by having it
actually show which line it wasn't able to parse.

fixes #2182
