raw-identify: use fallback if PATH_MAX not available

PATH_MAX is optional in POSIX, so define a fallback value if not
available. While ideally it should not be relied upon, a fallback value
is enough for a sample application.

Gbp-Pq: Name 0002-raw-identify-use-fallback-if-PATH_MAX-not-available.patch
