build: fix version extraction from non-git directory

https://github.com/ElementsProject/lightning/releases/download/v0.8.0/clightning-v0.8.0.zip
extracts into "clightning-v0.8.0".

https://github.com/ElementsProject/lightning/archive/v0.8.0.tar.gz
extracts into "lightning-0.8.0".

Tweak the regular expression in the Makefile to support both (extract
0.8.0 from either one). Also, downloading an arbitrary version, based on
git commit id:

https://codeload.github.com/ElementsProject/lightning/tar.gz/eb2b225c?dummy=/filename_this_is_irrelevant.tar.gz
extracts into "lightning-eb2b225c".

so, support extracting "eb2b225c" from that.
