create alias covering_own_breasts (69) -> covering_breasts (6579)
create alias covering_own_crotch (37) -> covering_crotch (5982)
create alias covering_own_eyes (24) -> covering_eyes (972)
create alias covering_own_pussy (7) -> covering_pussy (399)
create alias covering_own_face (45) -> covering_face (2691)

Reason: These are unnecessarily specific, as a combo search of the relevant tag with covering_self should return the same content.

covering_own_mouth is excluded because it's the only one of these tags with significant use and existing implications.
