Martin Vogel 8fc19497e7 Add cbm_replace_binary: unlink-before-write for update command ...

TDD: two tests (overwrite read-only file, create new file) written
first, then cbm_replace_binary() implemented and wired into update.

The update command failed when the existing binary had no write
permission (e.g., 0500). unlink() only requires write permission on
the parent directory, not the file itself, so removing first then
creating with O_CREAT | 0755 handles all permission combinations.

Fixes #114.
