fix conflicting mips and powerpc definitions for TIOCSER_TEMT macro

Commit 3517d74a5e04a377192d1f4882ad6c8dc22ce69a changed the token in
sys/ioctl.h from 0x01 to 1, so bits/termios.h no longer matches. Revert
the bits/termios.h change to keep the headers in sync.

This reverts commit 9eda4dc69c33852c97c6f69176bf45ffc80b522f.
