1. Verify payload length early on …

   I was looking at something else here and happened
   to notce we didn't seem to be sanity
   checking the length of strings in some places.
   
   Looking harder, first thing I checked is a
   really long filename in a dump file; that's
   fine, we do check that.
   
   Next I tried symlinks, and that caused a
   an assertion trip process abort (thankfully at least)
   deep in the bowels of the EROFS generation.
   
   Fix this by checking the payload length against PATH_MAX.
   
   Also:
   
   - Add the missing error checking in mkcomposefs
   - Add test infrastructure for "should fail" dumpfiles
