dependencies: check for MakeMaker Perl module

ExtUtils::MakeMaker is one of the Perl Core modules usually packaged in
Perl package for a Debian/Ubuntu based system.
For a Fedora based system, each Perl Core modules have their own RPM
package. So install only Perl package is not enough.

Fixes:
>>> host-libxml-parser-perl 2.41 Configuring
[...]
perl `which perl` Makefile.PL
Can't locate ExtUtils/MakeMaker.pm in @INC (you may need to install the ExtUtils::MakeMaker module)

Add a new Perl module check in dependency.sh.
