    mail/courier-imap: Apply hack to fix reported runtime issue
    
    A runtime issue has been reported at [1] which causes courier-imap
    to not work properly.
    
    Experimenting shows this issue disappears by downgrading
    devel/libunistring to previous version 1.2, but no clear reason why
    has been uncovered.
    
    This commit applies a patch similar to what is suggested in [1]
    that makes it work as expected.
