Bug 37972: Allow selection of tab in patron's summary table by query param

To test:
1) Apply the patch
2) Place a hold on any biblio with the 'koha' patron for example
3) Authenticate in the OPAC with the patron you picked in step 1
4) Open opac-user.pl with the query param 'tab': /cgi-bin/koha/opac-user.pl?tab=opac-user-holds
5) Note that the holds tab in the patron's user summary is automatically selected
6) Sign-off

I'm totally open to renaming the query param, so if you have a suggestion that's more consistent
with the rest of koha, I'm all ears.
