relibc: add CRTSCTS and TIOCM serial port constants for Redox

Browse Source 
- termios/redox.rs: CRTSCTS hardware flow control flag
- sys_ioctl/redox/mod.rs: TIOCM_LE/DTR/RTS/ST/SR/CTS/CAR/CD/RNG/RI/DSR
  modem line constants, TIOCMGET/TIOCMSET ioctl numbers

These enable qtserialport to compile without source-mutating python
injections that wrap serial port code in #ifdef guards.
