postgresql: Break perl RDEPENDS

Currently, any non-native recipes that inherits cpan-base ends up
with an image RDEPENDS on perl (via
https://git.yoctoproject.org/poky/tree/meta/classes-recipe/cpan-base.bbclass?h=scarthgap#n14)

If you are building an image and desire to have Postgresql installed
but NOT perl, this creates a problem. This changeset attempts
to fix this shortcoming by not inheriting cpan-base directly.

Note this work is a continuation of attempts to change cpan-base:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=15563

The Postgresql build system uses perl, so add it as a DEPENDS. This
happened previously via the "inherit cpan-base" directive.

I've validated this recipe successfully packages with and without
the perl PACKAGECONFIG in Scarthgap.
