lib/sstatesig/find_siginfo: raise an error instead of returning None when obtaining...

Suppressing the error and returning None can result in a delayed failure:

It is not clear why the os.stat() error occurs to begin with (it shouldn't), so rather than
adding further workarounds, let's get diagnostics at the source first, so we understand
what is going on.
