LoongArch: Undef __NR_fstat and __NR_newfstatat.

In Linux 6.11, fstat and newfstatat are added back. To avoid the messy
usage of the fstat, newfstatat, and statx system calls, we will continue
using statx only in glibc, maintaining consistency with previous versions of
the LoongArch-specific glibc implementation.
