Bug 18777: Translatability: Get rid of exposed tt directives in opac-memberentry.tt

Bug 18777: Translatability: Get rid of exposed tt directives in opac-memberentry.tt

The file opac-memberentry.tt exposes template directives to translation where
translators should not be confronted with.

Example from po file:
"%s [%% UNLESS hidden.defined('B_address') && hidden.defined('B_address2') && "
"hidden.defined('B_city') && hidden.defined('B_state') && hidden."
"defined('B_zipcode') && hidden.defined('B_country') && hidden."
"defined('B_phone') && hidden.defined('B_email') && hidden."
"defined('contactnote') %%] "

To test:
- Apply patch
- Verify that advanced search in OPAC the page 'your personal details'
  behaves as before
- Verify that you can change values and submit an update request
- Create a new translation for a 'language' aa-AA (perl translate create aa-AA)
- Verify that template directives ar no longer exposed in aa-AA-opac-bootstrap.p

NOTE: Followed test plan similar to bug 18776 comment 3.
