lib/Makefile.inc: Generate placeholder spd.bin in lib/Makefile.inc
When a new variant is created, it needs to have a path to its SPD binary
defined. Currently, this is done by setting SPD_SOURCES to a placeholder
SPD file, which just contains zero bytes.
To remove the need for a placeholder file, automatically generate a
single-byte spd.bin in lib/Makefile.inc when SPD_SOURCES is set to the
marker value 'placeholder'.
BUG=b:191776301
TEST=Change cappy/memory/Makefile to `SPD_SOURCES = placeholder`. Build
and check that spd.bin contains a single zero byte.
