`alembic`[1] is a database migration tool which is invoked from the CLI
when installing the telegram bridge, but never needed during the
runtime.

The reason why `alembic` is required here is to ensure that it
exists in the Python environment when deploying the bridge. However
`alembic` requires `mautrix-telegram` in its environment to create a
database schema from the Python models.

Such a dependency relation may be possible with tools like virtualenv,
however it'll result in an infinite recursion at evaluation time in Nix.

With this patch, `mautrix-telegram` doesn't depend on `alembic` anymore
and provides a patched alembic (`pkgs.mautrix-telegram.alembic`) which
has `mautrix-telegram` in its path.

Update deps, enable tests.

Rofi-pass as of a year ago added support for OTP passwords. This
dependency is "optional" but extremely nice to have as a default.

This uses systemd's system.conf/user.conf "DefaultEnvironment" feature
to set the allocator's LD_PRELOAD near-globally.
