Bug 18695: Translatability: Get rid of [%% INCLUDE in translation for circulation.tt

Bug 18695: Translatability: Get rid of [%% INCLUDE in translation for circulation.tt

The file circ/circulation.tt exposes the following line to translation:
%s %s [%% INCLUDE 'blocked-fines.inc' fines = chargesamount %%] %s %s
Translators should not be confronted with code internals.

This patch fixes it by removing a line break.

To test:
- Verify that code change makes sense
- Run QA tools in newest version (check for line breaks in tt directives)
- Bonus test: Create a "language" aa-AA (perl translate create aa-AA
  from folder misc/translator, verify that line mentioned above do
  no longer appear in aa-AA-staff-prog.po )
