Fix Fl::add_timeout() under Linux (STR 3516)

Browse Source 
See comment 14 (excerpt):

"The current implementation basically handles add_timeout() the same
way as repeat_timeout(), i.e. add_timeout() *calls* repeat_timeout().
However, repeat_timeout() intentionally *corrects* the timeout value
by the value found in the global variable 'missed_timeout_by' which
is set when the timer expires, directly before the timer callback
is called. This variable is never reset."

This commit resets the variable as necessary in Fl::add_timeout().
