When building ikiwiki-hosting in a container/autobuilder environment where it is not already installed, the makesite.t test fails because /etc/ikiwiki-hosting/ikiwiki-hosting.conf doesn't exist yet.

This seems to have been triggered by adding a call to IkiWiki::Hosting::readconfig in the makesite plugin.

Proposed fix (git fetch https://git.pseudorandom.co.uk/git/smcv/ikiwiki-hosting.git build-time-makesite-test)
