[PATCH] [compiler-rt] Remove struct_termio_sz from sanitizer_platform_limits_posix.cpp

The `struct termio` and its associated code have been removed from glibc as they are considered obsolete. This change removes the corresponding code in compiler-rt to maintain compatibility.

Additionally, the check for `struct_termio_sz` specific to Android has been removed. There is no guarantee that the Linux kernel or Google will continue supporting `struct termio`, and its removal aligns with the deprecation in glibc.
