flashrom: Update to 1.3.0, package libflashrom

Notably, the meson args for programmers changed from a series of
individual 'config_$foo>, config_$bar' to a list of
'programmer=$foo,$bar'

The patches were all either already merged upstream (or similar ones, at
least), or aren't useful (bitbang_spi is no longer a separated
programmer; it's included in the defaults).
