dracut: add 'git' recipe with DEFAULT_PREFERENCE = -1

This updates to a revision that has PR1260, which uses ELF entries to
get dependencies instead of (cross-)ldd. This makes it useable as a tool
to generate initramfses using cross tools, in e.g. do_rootfs.

Since this is not using a tagged release and changes the base logic, add
it as a non-default option using DEFAULT_PREFERENCE = -1.

Extend to native(-sdk) to accomplish just that.

The host-built initramfs (using a custom bbclass) as well as the
on-target built initramfs have been tested on qrb2210-rb1-core-kit and
qcs6490-rb3gen-core-kit machines and work as intented.
