Mark __internal_statvfs[64] with attribute_hidden [BZ #18822]

Mark __internal_statvfs[64] with attribute_hidden to allow direct access
to them within libc.so and libc.a without using GOT nor PLT.

	instead of <sys/statvfs.h>.
	(__internal_statvfs): Removed.
	* sysdeps/unix/sysv/linux/fstatvfs64.c Include "internal_statvfs.h"
	instead of <sys/statvfs.h>.
	(__internal_statvfs64): Removed.
	* sysdeps/unix/sysv/linux/internal_statvfs.c: Include
	"internal_statvfs.h" instead of <sys/statvfs.h>.
	* sysdeps/unix/sysv/linux/internal_statvfs.h: New file.
	* sysdeps/unix/sysv/linux/statvfs.c Include "internal_statvfs.h"
	instead of <sys/statvfs.h>.
