Subject: [PATCH] dracut.sh: add library-path option

Dracut.sh calls out to dracut-install which will use the default system
library paths. This causes issues if the host system doesn't have libkmod
installed.

Add the new option --library-path, which if set, exports LD_LIBRARY_PATH before
calling dracut-install
