to make Quicklisp happy. Small tweaks.

Be more violent in resetting release dependencies directories.
Fix make-release-tarball (double oops).
Export getcwd, chdir, with-current-directory from the driver.

Driver: Fix native-namestring on SCL; fix issues on CLISP:
Setting the *source-file-types* and *compiled-file-types* to nil

Fix enough-namestring in Makefile.
