lib/common.sh: add 'lock_close'; use it as appropriate.
`lock_close FD` is easier to remember than 'exec FD>&-`; and is especially easier if FD is a variable (though that isn't actually taken advantage of here). This uses Bash 4.1+ `exec {var}>&-`, rather than the clunkier `eval exec "$var>&-"` that was necessary in older versions of Bash. Thanks to Dave Reisner for pointing this new bit of syntax out to me the last time I submitted this (back in 2014, 4.1 had just come out).
