The package naming is confusing. It turns out we’ve been installing the
wrong libpcre version for ages, but haven’t noticed because the correct
version has previously been installed on the system by default.
It seems that Debian Bullseye doesn’t have the old libpcre installed by
default, so now we have to fix this package name and make sure it’s
installed in the CI images. Building it as a subproject is a pain.
