Use 64-bit system types for x86-64

	PR sanitizer/59018
	* sanitizer_common/sanitizer_platform_limits_linux.cc
	(struct_kernel_stat64_sz): Initialize to 0 if __x86_64__ is
	defined.
	* sanitizer_common/sanitizer_platform_limits_posix.h
	(__sanitizer_dirent): Use 64-bit d_ino/d_off if __x86_64__ is
	defined.
	(__sanitizer___kernel_uid_t): Typedef as unsigned if __x86_64__
	is defined.
	(__sanitizer___kernel_gid_t): Likewise.
	(__sanitizer___kernel_off_t): Typedef as long long if __x86_64__
	is defined.
