Bug 10564 - use OPACURLOpenInNewWindow in UNIMARCslim2OPACResults.xsl

Bug 10564 - use OPACURLOpenInNewWindow in UNIMARCslim2OPACResults.xsl

When using UNIMARC XSLT for OPAC detail page, if record has an 856$u,
its content is displayed as a link. The syspref OPACURLOpenInNewWindow
adds the option of opening in a new window (attribute target="_blank").

856$u is also used in UNIMARC results XSLT but the use of
OPACURLOpenInNewWindow syspref is missing. It exists for MARC21.

This patch adds the use of OPACURLOpenInNewWindow in UNIMARCslim2OPACResults.xsl.

Test plan :
- In a UNIMARC catalog, enable XSLT for OPAC results page
- Create a record with a link in 856$u and set second indicator to 0
- Set OPACURLOpenInNewWindow syspref on
- At OPAC, perform a search that contains the record
=> You should see the link : "Click here to access online"
- click on it
=> You shoud get to a new window (or tab depending on your browser configuration)
- Set OPACURLOpenInNewWindow syspref off
- re-perform the search
- click on the link
=> You shoud stay in same window
