Subject: [PATCH] fix(squash): apply FIPS and libpthread workaround

There are some workarounds in dracut.sh for FIPS/libpthread covering
some hidden lib dependency issues. These workarounds didn't take effect
for the squash loader since the squash loader is installed
independently. So apply these workarounds again.

Also skip the lib detection code, since these extra installed libs
are small, and squash loader contents are dropped after switch root,
won't be an issue to be always installed. And this makes the code
cleaner.

Resolves: #1990847
