target: a valid sha1 must be concatenated with the kernel version

Browse Source 
Some SoC vendors add several sha's to the kernel version string. This is
problematic for the KernelVersion class, which might identify the wrong one.

Fixing this issue by matching the following "git describe" pattern:

  <version>.<major>.<minor>-<rc>-<commits>-g<sha1>

Where commits is the number of commits on top of the tag, which is now a
member of the class.

Prior to this patch:

>> KernelVersion("4.14.111-00001-gd913f26_audio-00003-g3ab4335").sha1
3ab4335
>>> KernelVersion("4.14.111_audio-00003-g3ab4335").sha1
3ab4335

With the modified regex:

>> KernelVersion("4.14.111-00001-gd913f26_audio-00003-g3ab4335").sha1
d913f26
>>> KernelVersion("4.14.111_audio-00003-g3ab4335").sha1
None
