CONFIG_EFI_SBAT_FILE can be a relative path. When compiling with
objdir != srctree the build currently fails because it can't find
the file set in CONFIG_EFI_SBAT_FILE:
arch/x86/boot/compressed/sbat.S: Assembler messages:
arch/x86/boot/compressed/sbat.S:6: Error: file not found: kernel.sbat
Add $(srctree) as include dir for sbat.o.

x86/boot: Handle relative CONFIG_EFI_SBAT_FILE file paths
CONFIG_EFI_SBAT_FILE can be a relative path. When compiling using a different
output directory (O=) the build currently fails because it can't find the
filename set in CONFIG_EFI_SBAT_FILE:
arch/x86/boot/compressed/sbat.S: Assembler messages:
arch/x86/boot/compressed/sbat.S:6: Error: file not found: kernel.sbat
Add $(srctree) as include dir for sbat.o.
