Bug 16428: Use the biblio framework to know if a field is mapped

The subroutine _build_default_values_for_mod_marc takes the
frameworkcode in parameter, but ModItemFromMarc did not pass it.
It uses it to know if a field is mapped or not to a Koha field
(C4::Koha::IsKohaFieldLinked).
Consequently the default framework ("") was always used.

This bug has been found working on bug 13074 and has been put on a
separate bug report to ease the backport.

Test plan:
Without this change, the tests added by bug 16428 won't pass
