Bump HAL_PATH_MAX to 4096
Some bits in the code use realpath() with destination paths of size HAL_PATH_MAX. This potentially breaks on systems where PATH_MAX is bigger than HAL_PATH_MAX (which was 512 until now). Since we can't use PATH_MAX directly (due to platforms like GNU/Hurd, which apparently don't have it), just bump HAL_PATH_MAX to 4096 (as PATH_MAX is on Linux), to avoid potential buffer overflows and also fix hal on Linux when enabling FORTIFY in gcc. https://bugs.freedesktop.org/show_bug.cgi?id=25888
