Revert "loplugin:implicitboolconversion"

This is not needed; the problem was in the Fedora 25 epoxy headers:
They got badly broken in an update, and should not be used from C++
code. If you use Fedora 25, make sure to use --without-system-epoxy
for now. See https://bugzilla.redhat.com/show_bug.cgi?id=1431994

This reverts commit cbb2e6b7.
