util/genbuild: Fix style & shellcheck issues

There shouldn't be any change to functionality here - this should be
strictly cleanup.
- STYLE: Put variables inside braces.
- SHELLCHECK: Instead of 'var= ' to clear a variable, use 'var=""'
- SHELLCHECK: Put commands and command variables inside quotes.
- SHELLCHECK: Don't use variables inside the printf commands.
- OTHER: COREBOOT_BUILD needed a date format when the variables in the
our_date() function were put into quotes.  This format matches the
output of 'LANG="" LC_ALL=C TZ=UTC0 date'
