[PATCH v1] Include limits.h for PATH_MAX.

[Peter Seiderer]

Fixes the following compile failure when building with musl:

  find_event_devices.c: In function ‘find_event_devices’:
  find_event_devices.c:60:14: error: ‘PATH_MAX’ undeclared (first use in this function)
     char fname[PATH_MAX];
                ^~~~~~~~
