[bug #28934] execve(path, args) should take path as a a relative path if it doesn't contain slashes

[Emilio Pozuelo Monfort]

Follow-up Comment #7, bug #28934 (project hurd):

The attached two patches fix this by adding a new exec flag in Hurd,
EXEC_FILE_NAME, that will make the exec server to not look at PATH, but just
exec the name it's been passed, even if it doesn't contain slashes.

Then we add a new _hurd_exec_file_name() that will use EXEC_FILE_NAME.

I didn't think a lot about the new function name, but it would be possible to
change it or to deprecate _hurd_exec and create a new one that has a flags
arguments (to not have two different ones) or whatever.

I've tested the patches, they fix the bug and I haven't noticed any
regression.
