Description:

Symlinking `pxz` to `/usr/bin/xz` mkinitcpio is stuck in a `xz` loop because `mkinitcpio`s' functions concatenate kernel module file decompression into one `xz -d module1 module2 ...` command.

Changing `mkinitcpio` module decompression to separately each module fixes this issue and makes it `pxz` compatible.

# Steps to reproduce:

$ ln -s /usr/bin/pxz /usr/bin/xz
$ mkinitcpio -P
