Bug 11283: make restriction type translatable

The new restrictions system has different types:
MANUAL, OVERDUES and SUSPENSION.

Those are shown in the interface and seem to come directly from the
database, so they are not translatable.

As they are hardcoded translations should be possible and be handled in
the template.

Test Plan:
1) Create a patron with one of each type of restriction
2) Apply this patch
3) Note you see the type with only the first letter capitialized,
   this indicates you are seeing the translatable string

updated po files:
