compilers: avoid -Wunused-value compiler warning in CLikeCompiler.has_members()
Otherwise, `CFLAGS='-Wall -Werror' meson build` can fail detection:
void bar(void) {
struct stat foo;
foo.st_mtim.tv_nsec;
}
-----------
Command line: `cc ./project/build/meson-private/tmpqz_gi65d/testfile.c -o ./project/build/meson-private/tmpqz_gi65d/output.obj -c -O3 -Werror -Wall -D_FILE_OFFSET_BITS=64 -O0 -std=gnu99` -> 1
