faft: Cache ec_uart_regexp
Whenever we send EC UART command, we set ec_uart_regexp. However,
sometimes this value doesn't change and we are actually wasting time and
polluting the test log. Let's cache its value and avoid setting it to
the same value.
BUG=chrome-os-partner:34392
TEST=Run firmware_ECKeyboard and passed. Check there are no duplicated
ec_uart_regexp setting.
