Perl is now built as a basic dependency of the template

Perl is necessary to build Texinfo and later to build LaTeX. Until now we
were just using the host operating system's installation of Perl, but in
some instances that Perl can be too old and not suppor the features
necessary. With this commit, Perl is now built from source during the basic
installation step of the template.

This was reported by Idafen Santana Pérez, after trying the pipeline on an
Amazon AWS EC2 system (a Linux distro by Amazon for its cloud services).
