Nick Craig-Wood b259f8b752 cmount, mount, mountlib: make --read-only reject modify operations
Normally mount/cmount use `-o ro` to get the kernel to mark the fs as
read only.  However this is ignored by WinFsp, so in addition if
`--read-only` is in effect then return EROFS ("Read only File System")
from all methods which attempt to modify something.
