avfilter/drawtext: present 'hms' formatted 'pts' in 24h format

Browse Source 
HMS is formatted as HH:MM:SS.mmm, but, HH part is not limited to
24 hours. For example, the the drawn text may look like this:
243029:20:30.342. To present the timestamp in more readable and
user friendly format, this patch provides an additional option
to limit the hour part in the range 0-23.

Note: Actually the above required format can be obtained with
format options 'localtime' and 'gmtime', but,  milliseconds part
is not supported in those formats.

The second argument is an offset added to the timestamp.
If the format is set to @code{hms}, a third argument @code{24HH} may be
supplied to present the hour part of the formatted timestamp in 24h format
(00-23).
If the format is set to @code{localtime} or @code{gmtime},
a third argument may be supplied: a strftime() format string.
By default, @var{YYYY-MM-DD HH:MM:SS} format will be used.
