Fix serprog on FreeBSD
Using serprog on FreeBSD to read an SPI flash (MX25L6406) via an
Arduino Nano V3 with flashrom hangs after 5 seconds while reading. The
problem is that kernel method "ttydisc_rint" ignores some bytes. It
happens due to enabled IEXTEN local flag of termios. TTY cuts a few
bytes, Arduino reads 11264 bytes, but flashrom gets only 11244 bytes
and waits for the remaining 20 bytes.
The fix is simple: turn off the IEXTEN local flag.
Tested on Arduino Nano V3 + FreeBSD 12-CURRENT.
