[OE-core] [PATCH 1/2] lib/oe/sstatesig: fix finding native siginfo files in sstate-cache

[Paul Eggleton]

When comparing signatures with bitbake-diffsigs -t or bitbake -S
printdiff, we use this find_siginfo() function implemented in this
module to find the siginfo/sigdata files corresponding to the tasks
we're looking for. However, native sstate files go into a
NATIVELSBSTRING subdirectory and there was no handling for this when
asking about native recipes.

I'm not even sure why we were walking SSTATE_DIR in order to find
this - we don't need to, we just need to run glob.glob() on the filespec
we calculate, which should be a little bit more efficient.
