Add the -C flag to ./configure to enable caching, reducing redundant
resource fetching during builds when packages and the machine remain
unchanged. Caching may cause issues only if applied across different machines
or if packages are modified, neither of which is the case during the build.
* Also pass `$*` to `configure` when invoking `ci-build.sh`, so one can
e.g. run `./ci-build.sh --without-xscreensaver`

Because we trap the error signal and run a error handler, logs were not
printed. I moved the printing of test-suite.log to the error handler and
also added so that config.log is printed on failure.
* Add .builds/openbsd.yml for builds.sr.ht
* Update travis-build.sh -> ci-build.sh with OpenBSD case
* Fix libdl check in configure.ac (OpenBSD has libdl built-in)
* Fix some minor issues found when compiling on OpenBSD with GCC (e.g.
uninitialized variables)
