[RFC PATCH 1/3] xfstests: get some basic source tree info

[Ben Myers]

Grab some basic information about the souce trees being tested and save
it off for later.  This includes information about the git commit and
any patches which are applied.

Set SRCDIRS environment variable with paths to the sources you're
testing, colon delimited like PATH. 

e.g.

export SRCDIRS="/path/to/kernel:/path/to/xfsprogs:/path/to/xfsdump:/path/to/xfstests"
