Subject: [PATCH] unload.sh: support kexec unload when kexec_file_load is required
References: bsc#1186272

Some systems, such as those using secure boot, require the use of
the kexec_file_load syscall instead of kexec_load.

Using kexe -a -p -u will try the new kexec_file_load syscall first,
and if it is not supported, fall back to using the old kexec_load.
