app-admin/rsyslog: rev bump to ease migration to dev-db/mysql-connector-c

Commit 2c4290d31c8f478d318bab463840479137a8d675 replaced
virtual/libmysqlclient dependency with dev-db/mysql-connector-c atom
without a rev bump.

To avoid unecessary user interaction for users not using emerge's
--changed-deps=y because we are already pushing towards removal of
virtual/libmysqlclient (see commit 08b83d736f77fd5dffa9cd5f6b1b44771726ce94),
this commit will now force the re-installation through rev bump
to ease migration.
