Subject: [PATCH 10/10] Makefile: use FIXED_TIMESTAMP for mkstandalone if set

mkstandalone sets timestamps for files which can be overriden by a fixed_timestamp.
This makes it possible to build reproducible builds for coreboot.

To build a reproducible build of grub for coreboot do:
make default_payload.elf FIXED_TIMESTAMP=1134242
