Previously, in a remote directory, '(eshell-get-path)' would return a
list of strings like "/ssh:localhost://usr/bin". While that shouldn't
break most things, it's not strictly correct either. See bug#65551.
* lisp/eshell/esh-util.el (eshell-get-path): Use 'concat' instead of
'file-name-concat'.
* test/lisp/eshell/esh-util-tests.el: Require 'tramp' and
'eshell-tests-helpers'.
(esh-util-test/path/get, eshell-util-test/path/get-remote): New tests.
