Make _get_efi_bootloaders return relative paths

To make this function useful for purposes other than efibootmgr
entries, this change moves the path manipulation to _run_efibootmgr.

This change also adds boot*.efi entries to BOOTLOADERS_EFI so that it
includes every entry in the UEFI Spec 2.9[1] Table 3-2 UEFI Image
Types.
