[flang][driver] Make driver accept `-module-dir<value>` 

`-module-dir` is Flang's equivalent for `-J` from GFortran (in fact,
`-J` is an alias for `-module-dir` in Flang). Currently, only
`-module-dir <value>` is accepted. However, `-J` (and other options for
specifying various paths) accepts `-J<value>` as well as `-J <value>`.
This patch makes sure that `-module-dir` behaves consistently with other
such flags.
