mip: Make mip.install() skip /rom*/lib directories.

dpgeorge · dpgeorge · commit 96e17b65d128 · 2025-03-11T16:27:09.000+11:00
If a ROMFS is mounted then "/rom/lib" is usually in `sys.path` before the
writable filesystem's "lib" entry.  The ROMFS directory cannot be installed
to, so skip it if found.
