cbfstool locate: Implement alignment switch --align/-a

Browse Source 
cbfstool usage change:
 "-a" for "cbfstool locate" can specify base address alignment.

To support putting a blob in aligned location (ex, microcode needs to be aligned
in 0x10), alignment (-a) is implemented into "locate" command.

Verified by manually testing a file (324 bytes) with alignment=0x10:
 cbfstool coreboot.rom locate -f test -n test -a 0x10
 # output: 0x71fdd0
 cbfstool coreboot.rom add -f test -n test -t raw -b 0x71fdd0
 cbfstool coreboot.rom print -v -v
 # output: test                           0x71fd80   raw          324
 # output:  cbfs_file=0x71fd80, offset=0x50, content_address=0x71fdd0+0x144

Also verified to be compatible with old behavior by building i386/axus/tc320
(with page limitation 0x40000):
 cbfstool coreboot.rom locate -f romstage_null.bin -n romstage -P 0x40000
 # output: 0x44
 cbfstool coreboot.rom locate -f x.bin -n romstage -P 0x40000 -a 0x30
 # output: 0x60
