move webapp build deps under Assistant build flag

git-annex.cabal: Move webapp build deps under the Assistant build flag so
git-annex can be built again without yesod etc installed.

Commit 78440ca37d got rid of the webapp build
flag to work around what was apparently a cabal bug. It moved the webapp
build deps to the main build-depends list. But that prevents building
git-annex when yesod etc are not installed.

Putting them under the Assistant build flag seems to not tickle that cabal
bug, and lets git-annex build automatically with the assistant disabled
when the webapp build deps are not installed.

I hypotehesize that the problem may have involved build-depends nested
behind two build flags. Also, cabal clean may need to be run in order
for cabal to find the right solution after this change, when building in
a directory where cabal configure had been run before.

Also moved 3 modules that are needed to build git-annex w/o the assistant
out from under the Assistant build flag.
