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.
