[OE-core] [zeus 6/6] sstatesig: Improve debug output if getpwuid() fails

[Armin Kuster]

From: Richard Purdie <richard.purdie at linuxfoundation.org>

If getpwduid fails, we don't see which file it failed on which is key information
to aid debugging. Print this information when exceptions are raised.
