Fix project.el commands in "transient" projects

* lisp/progmodes/project.el (project--files-in-directory): Run
local DIR directory names through 'expand-file-name', so that "~/"
is expanded, in case the shell doesn't or the shell's notion of
the home directory is different from that of Emacs.  (Bug#40940)
