lshw: bump version to B.02.18

lshw: bump version to B.02.18

Version B.02.17 was found to be unstable on recent HW.

Status of the patches:

 - The patch allowing to add extra values to the LIBS variable has
   been refreshed, and changed to a Git formatted patch.

 - The two patches from git.alpinelinux.org were needed for lshw to
   build with the musl C library, but they have been merged upstream
   (commit cd690bff1516b40fecd5ec4a7f6619e5bffc3cf0).

 - The last patch was taken from upstream, and therefore already
   merged, and now part of B.02.18.

This patch was tested with kernel 4.4.16.

[Thomas:
 - better explanation about patches
 - re-add patch from Gustavo about LIBS, since it is really needed.]
