lib/oe/sstatesig.py: add signature data query function
Add a function that can be used from BitBake code which will find signature data (sigdata/siginfo) files based on specified criteria, and hook it into BitBake as bb.siggen.find_siginfo. (From OE-Core rev: 9f0453c29891e32f8038c4bbc22ada28bfbf818a) Signed-off-by: Paul Eggleton <paul.eggleton@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
