Tests: Increase tolerance in blocking test

If the machine executing the tests is especially slow, this can make the
test fail:
https://launchpadlibrarian.net/161805969/buildlog_ubuntu-trusty-amd64.libaccounts-glib_1.16bzr182trusty0_FAILEDTOBUILD.txt.gz

Therefore, increase the test timeout.
Fix build with -Werror

Building libaccounts-glib with -Werror cflags fails with error:

ag-provider.c: In function 'ag_provider_get_single_account':
ag-provider.c:444:266: error: return makes integer from pointer without
a cast [-Werror]
Add multiarch annotations to libaccounts-glib0 and libaccounts-glib-tools.
AgManager: expose DB timeout parameters as properties
AgManager: implement GInitable

Returning NULL from the GObject constructor is not supported; the
GInitable interface was created especially for this.
AgManager: allow instantiation with no D-Bus

One use-case for this functionality is initializing the accounts
database (and parsing the service files) from a process which doesn't
have access to D-Bus.
Tests: increase timeout in test_store_locked_cancel

Timeout proved too short on a smartphone hardware.

Python: restore functionality of Accounts.Manager()

The default implementation for PyGObject constructors is to call
g_object_new(). However, objects which implement the GInitable interface
must be created with g_initable_new() (or alternatively,
g_initable_init() needs to be called right after the object has been
created), but PyGObject doesn't do that for us.
Therefore, we override the Accounts.Manager() constructor to call
ag_manager_new(), which we trust does the right thing.
