vmd: relax absolute path requirement for configtest

[Omar Polo]

Hello,

after vmd.c rv 1.142 vmd(8) errors when ran with a non-absolute path;
this makes using -n (configtest) slightly more verbose, as the full
path is needed and not just `vmd -n'.

here's an attempt at relaxing the requirement for the -n case only.
since we're not going to run any vm it should be fine, but apologize
if I've missed something.


Thanks,

Omar Polo
