main/postmarketos-mkinitfs: Avoid storing initramfs-extra twice

At the moment we store the same initramfs-extra twice on the file system:

• /boot/initramfs-<flavor>-extra
• /var/cache/postmarketos-mkinitfs/initramfs-<flavor>-extra_<hash>

The second copy is exactly the same file, just with the <hash> (for caching) appended to the filename.

We can avoid this by appending the hash directly to the filename on the boot partition, i.e.

• /boot/initramfs-<flavor>-extra_<hash>

This is possible because we only reference initramfs-extra from the main initramfs, and we already replace the path in it dynamically. It will just let the main initramfs load -extra_<hash> instead of just -extra.

This saves a few megabytes of disk space on the rootfs.
