libsanitizer: Make malloc/realloc/free safe via 'pointer_is_mine'

	      * libsanitizer/asan/asan_malloc_linux.cc: check pointers
	      before calling forwarding.

This change will lead to possible failures inside glibc in cases of free()'ing
wild pointers.

In usual case ASan should handle this case and provide appropriate backtrace
and error report, but this mode is not compatible with interceptor switching
functional, so we explicitly disabling it.
