LoongArch: Fix inconsistency in SHMLBA macro values between glibc and kernel
The LoongArch glibc was using the value of the SHMLBA macro from common code, which is __getpagesize() (16k), but this was inconsistent with the value of the SHMLBA macro in the kernel, which is SZ_64K (64k). This caused several shmat-related tests in LTP (Linux Test Project) to fail. This commit fixes the issue by ensuring that the glibc's SHMLBA macro value matches the value used in the kernel like other architectures.
