runtime(vimgoto): Fix gf in Vim script

Problem: `gf` in Vim script fails if multiple target files exist.
Solution: Use globpath() which returns an array.

In a Vim script, `gf` on `some#func()` will jump to `autoload/some.vim`.
In this case, if there are multiple `autoload/foo.vim`s in
'runtimepath', `globpath(&runtimepath, path)` will return multiple
paths, separated by newlines.
As a result, the second and subsequent paths will be executed as
commands in `autoload/vimgoto.vim:195`, causing an error.
This change fixes this issue by making the result of `globpath()` an
array.

closes: #19379
