Add gender for upload log entries

With Icd8662ecb9eb0f6c0ff9841bdbd5736d6dd0d015 the log for uploads was
migrated to the new system, but no formatter was set to use the new
system also on Special:Log.
There is no need for an extra formatter class, because at the moment
there is nothing extra to format.

Added the new messages and adjust them. Now upload logs supports gender.
The old messages are kept for IRC where there were already in use.
This also hide the params added with
Icd8662ecb9eb0f6c0ff9841bdbd5736d6dd0d015 on Special:Log, because there
are not needed for i18n.
