[compiler-rt] [sanitizer] Remove usage of termios ioctl constants on Linux (PR #149140)

[via llvm-commits]

https://github.com/trcrsired created https://github.com/llvm/llvm-project/pull/149140

glibc 2.42 made all usage of termios ioctl constants strictly internal

Therefore, we remove all usage for those removed constants.

This should only apply for Linux.

Fix #149103
