Aliases for male specific tags

BUR #5356 has been approved by @evazion.

create alias cleavage_(male) -> male_cleavage
create alias sandwich_(male) -> boy_sandwich
create alias harem_(male) -> male_harem
create alias masturbation_(male) -> male_masturbation
create alias prostitution_(male) -> male_prostitution
create alias lactation_(male) -> male_lactation
create alias sucking_nipples_(male) -> sucking_male_nipple
create alias pregnancy_(male) -> male_pregnancy

To make the tags easier to find in the autocomplete.

If I missed any other tags do mention them.

The bulk update request #5356 (forum #184938) has been approved by @evazion.

I don't love having to make a million aliases for every tag to make autocomplete work. These will probably be removed someday when autocomplete learns how to do this automatically.
