Fix ejabberdctl output formatting (#3979)

Browse source 
ECMA-48 SGR sequence ESC [21m is actually 'set double underline' but was
incorrectly implemented as 'set normal intensity' in Linux prior to
4.17.

The correct sequence for 'set normal intensity' is ESC [22m, which fixes
output formatting of 'ejabberdctl' and 'ejabberdctl help' on macos.
