main/postmarketos-initramfs: new aport (MR 3895)

This package contains base file and module lists for the initramfs /
initramfs-extra archives, along with the init.sh

The primary reason for doing this is so that changes to these
files/lists can be properly versioned (in pkgver), and (re)building
mkinitfs itself is no longer required for these changes.

- Add base file list for initramfs. The dirs at path
  /usr/share/postmarketos-mkinitfs/* are "new" in mkinitfs 2.0

- Install default modules to /usr/share

- Install system config to /usr/share/mkinifs

- Add base files for -extra archive

- Create user config dirs

- Update hook dirs in init.sh, change from mkinitfs 2.0

- Remove splash images, obsolete since pbsplash

- Support uncompressed initramfs-extra
