Fix regression that broke dracut initramfs generation 

Based upon @ryao's initial fix for 1c73494394fc9de9283b3fd4f00bcdf4bd300a7
( 5e9843405f63fdabe76e87b92b81a127d488abc7 ) this one also uses
`command -v` instead of `type`, but additionally only applies the
fix to close zfsonlinux/zfs#4749 when `libgcc_s.so.1` has not been included
by dracut automatically (verified by whether `zpool` links directly to
`libgcc_s.so`), as well as change the fallback option to match `libgcc_s.so*`.
