[LTP] [PATCH] resource: explicitly define _LARGEFILE64_SOURCE

[LTP] [PATCH] resource: explicitly define _LARGEFILE64_SOURCE

[Li Wang]

Fix compilation errors on Alpine Linux (musl) by explicitly defining
_LARGEFILE64_SOURCE instead of _GNU_SOURCE. This ensures that 64-bit
resource limit structures (e.g., struct rlimit64) are properly exposed
in <sys/resource.h>.

To resolve the compiling error on Alpine:
