Ensure PATH_MAX is defined (ticket #3) Adam Tkac

- POSIX doesn't require PATH_MAX to be defined as constant, and Hurd
  doesn't define it...
- deal with it just once in system.h for now, the proper fix is to get
  rid of needing it at all (ie add a mallocing realpath() clone to librpmio)
- patch from Adam Tkac
