Patch to add a force-key-unit flag to hlssink.

If you wish to use hlssink without (re-)encoding, nothing will be listening to
the force key unit messages, resulting in errors:

gsthlssink.c:503:schedule_next_key_unit:<hlssink0> Failed to push upstream
force key unit event

This patch adds a flag preventing the force key unit messages to be sent,
relying on existing key frames. This may (and probably will) result in
non-standard-adhering segments, but if you don't care about that, this will do
fine.

It will set multifilesink->next-file to 2 instead of 3 to make this work.
