Bug 10459: Borrowers should have a timestamp

This patch adds a timestamp column to the borrowers table in kohastructure
and updatedatabase. (And also to the deletedborrowers table.)
A timestamp may be useful in synchronizing with external systems (among other
reasons).

Test plan:
Run updatestructure on an existing database, or install a new one.
Verify that the borrowers table has a timestamp now.

Tested updatestructure and running kohastructure.sql.
Passed t/db_dependent/Members.t.

updatedatabase.pl did not apply. I edited and then run it. Columns were added as expected.
