Bug 15182: Conditionally load Koha::NorwegianPatronDB

Bug 15182: Conditionally load Koha::NorwegianPatronDB

This patch loads Koha::NorwegianPatronDB if it can, or adds a warning
to the log if it can't load it.

Since the Koha::NorwegianPatronDB functionality in C4::Members is
wrapped in system preferences, the loading of the module is
irrelevant unless one actually wants to use the module and its
associated functionality.

NOTE:

This patch fixes a problem where we were getting errors saying
Crypt::GCrypt couldn't be loaded even though it's not a required
dependency.

This patch will likely only affect people not using Debian-based
systems where libcrypt-gcrypt-perl is available. The current
version of Crypt::GCrypt doesn't build so it's not an option
for most non-Debian users to install this not required
dependency in order to work around this issue...
