Instead of trying every possible compression method until the right one is found, parse the header of the initramfs image to get the right one and use it without hiding possible decompression errors, using the same logic that is implemented in lsinitrd.sh.

For that, refactor lsinitrd.sh moving common code to dracut-functions.sh. In particular:

• get_machine_id
• get_default_initramfs_image [<kernel_version>]
• has_early_microcode <initramfs_image>
• get_decompression_command <initramfs_image_header>

Also, added a new get_dollar_boot function to get the $BOOT partition placeholder, as defined in the Boot Loader Specification. If bootctl is available, use it to support a possible XBOOTLDR partition, otherwise, check only the ESP, as before.

Also refactored dracut.sh using these new functions to get the outfile path.
