Subject: mkinitcpio: dedupe MODPATHS array before installation

The only reason this has to be done is because of the Kconfig option
that reuses the ext4 module for ext[23], thereby aliasing ext[23] to
ext4. This is (currently) the only case in the whole kernel where valid
module names magically become aliases.
