distro: Change $DISTRO_{PATCH,BOOTSTRAP}_DIRECTORY to search paths.
* distro.scm (not-colon): New variable. (%patch-directory): Rename to... (%patch-path): ... this. Turn into a list. Expect $DISTRO_PATCH_PATH to be a colon-separated search path. (%bootstrap-binaries-directory): Rename to... (%bootstrap-binaries-path): ... this. Likewise. (search-patch, search-bootstrap-binary): Adjust accordingly. * pre-inst-env.in: Change to use `DISTRO_PATCH_PATH' and `DISTRO_BOOTSTRAP_PATH'.
