dracut: Update to v103 and add patches

Switch to the dracut-ng fork which is maintained. Add several patches of note:

Invalidate depmod index module. Used for initrd extension
Skip firmware installation in initrd. Used for linux-firmware initrd extension
Skip hwcaps directories when processing libs. Ensures that built initrds are usable on machines with a lower ISA than supported by hwcaps
Stateless ldconfig configuration
De-compress kbd files prior to initrd creation. Improves initrd compression ratio
