[PATCH v3 12/12] serve.[ch]: don't pass "struct strvec *keys" to commands

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

The serve.c API added in ed10cb952d3 (serve: introduce git-serve,
2018-03-15) was passing in the raw capabilities "keys", but nothing
downstream of it ever used them.

Let's remove that code because it's not needed, and because if and
when we need to pass data about the advertisement (I have some WIP
patches for that), it makes much more sense to have the serve.c parse
the capabilities, and then pass specific information we need down than
expecting its API users to re-do their own parsing of the raw data.
