[PATCH 10/11] tests: Avoid gnulib replacements in mocks

[Roman Bolshakov <r.bolshakov@xxxxxxxxx>]

gnulib headers change stat, lstat and open to replacement functions,
even for function definitions. This effectively disables standard
library overrides in virfilewrapper and virmockstathelpers since they
are never reached.

Rename the functions and provide a declartion that uses correct
assembler name for the mocks.

This fixes firmware lookup in domaincapstest on macOS.
