Assistant: Fix installation of menus, icons, etc when run from within runshell.

runshell followed by git annex webapp didn't install that stuff, because
GIT_ANNEX_APP_BASE is not set. Running git-annex.linux/git-annex-webapp did
install that stuff, since that script set the env var. I noticed this with
the termux port whose instructions currently go that way.

Seems the right thing to do is to move the env var setting to runshell.
