runtime(ftplugin): allow to exec if curdir is in PATH

Browse Source 
In case the current directory is present as valid $PATH entry, it is OK
to call the program from it, even if vim curdir is in that same
directory.

(Without that patch, for instance, you will not be able to open .zip
files while your current directory is /bin)
