rgw: Clarify naming of case-change functions

It is not clear that the lowercase_http_attr & uppercase_http_attr
functions replace dashes with underscores. Rename them to match the
pattern established by the camelcase_dash_http_attr function in
preperation for more case-change functions as needed by later fixes.
