Bug 11252: remove deprecated -munge-config switch from rebuild_zebra.pl

The -munge-config switch has been deprecated for years, and
trying to use it would either not work at all or, if it did "work",
almost certainly damage one's Zebra configuration for Koha.

This patch removes this switch.

To test:

[1] Run rebuild_zebra.pl and verify that no mention is made
    of -munge-config.
[2] Run rebuild_zebra.pl to index records in one's test database
    and verify that there are no regressions.

Bug 10453: fix unintended password reset when updating child to adult

ModMember supposes the password given in parameter is the
password string, so if it receives the encrypted password,
it will encrypt it again! By simply deleting the password key
from the hash, ModMember leaves the password unchanged.

Test plan:
1/ Create or choose a child patron
2/ Update it to an adult category using the
   "Update child to adult patron" link
3/ Try to log in at the OPAC with this patron: It is not
   possible, the password has changed
4/ Apply the patch and try again previous steps
