Because you never really know what else lit might prepend to the PATH,
as the PR demonstrates.  It's just more solid to say what you really
mean.  As a bonus, when things fail, the run script output by lit will
include the full paths so you know exactly what ran.

BTW, I just reverted the patch as it causes some darwin failures.  I
don't have a darwin system to test on and all the error message says is
"multiple repeat."  It means something is wrong with a regexp but I
don't have an easy way to figure out what.  Is anyone with a darwin
system able to investigate?  I'll blindly poke around for now.  :)
