vim-patch:8e25d91: runtime(dist): verify that executable is in $PATH

Otherwise, if the executable to be verified does not exist,
this would cause a false-positive in the 'IsSafeExecutable()' check,
because 'exepath(executable)' returns an empty string and
'fnamemodify('', ':p:h')' returns the current directory and as a result
the 'IsSafeExecutable()' returns false (for the wrong reason).
