selftests/powerpc: Use date instead of EPOCHSECONDS in mitigation-patching.sh
The EPOCHSECONDS environment variable was added in bash 5.0 (released
2019). Some distributions of the "stable" and "long-term" variety ship
older versions of bash than this, so swap to using the date command
instead.
"%s" was added to coreutils `date` in 1993 so we should be good, but who
knows, it is a GNU extension and not part of the POSIX spec for `date`.
