serial: Call set_custom_baudrate() thrice
Call the function before tcsetattr() settings are known, then again
with settings prepared but not yet applied and finally a third time
after tcsetattr().
Darwin support needs this change; there custom_baud code must be
called to modify the settings passed to tcsetattr() and then again
after tcsetattr() returns.
The change should be non-functional on all currently supported systems;
current code calls set_custom_baudrate() before any tcsetattr()
settings are prepared, so we have three stages in total.
This change originates from discussion of the macOS patch proposed by
Denis Ahrens in https://review.coreboot.org/c/flashrom/+/67822
