How I did it
How to verify it

…route counter timeout (sonic-net#1171)

### Description of PR

[snmp] fix _test_snmp_bgp_down using wrong OID and increase route
counter timeout

`_test_snmp_bgp_down` hardcoded `INET_CIDR_ROUTE_NUMBER_OID`
(`1.3.6.1.2.1.4.24.6.0`)
in 3 places instead of using the `snmp_oid` parameter passed by callers.
This caused
`test_snmp_ipCidrRouteNumber_bgp_down` to query the wrong OID
(inetCidrRoute `.6.0`
instead of ipCidrRoute `.3.0`), leading to timeout failures.

Also increase `ROUTE_COUNTER_TEST_INTERVAL` to 5s and
`ROUTE_COUNTER_UPDATE_TIMEOUT`
to 10s (from 3s/6s) since inetCidrRoute takes 6-12s to repopulate after
BGP restart,
making the 6s timeout too tight.

### Approach
#### What is the motivation for this PR?

`test_snmp_ipCidrRouteNumber_bgp_down` was failing on gold207 because
`_test_snmp_bgp_down`
hardcoded the wrong SNMP OID (`INET_CIDR_ROUTE_NUMBER_OID =
1.3.6.1.2.1.4.24.6.0`) instead
of using the `snmp_oid` parameter. The `ipCidrRoute` test should query
OID `.4.24.3.0`
but was querying `.4.24.6.0` (inetCidrRoute).

Additionally, the 6s recovery timeout was insufficient — inetCidrRoute
takes 6-12s to
repopulate after BGP restart.

#### How did you do it?

- Replace 3 hardcoded `INET_CIDR_ROUTE_NUMBER_OID` references in
`_test_snmp_bgp_down`
  with the `snmp_oid` parameter
- Increase `ROUTE_COUNTER_TEST_INTERVAL` from 3s to 5s and
`ROUTE_COUNTER_UPDATE_TIMEOUT`
  from 6s to 10s in `tests/common/fixtures/route_counter.py`

#### How did you verify/test it?

Observed test failure on gold207, analyzed root cause from logs, and
verified the fix
addresses both the wrong-OID issue and the timing issue.

#### Any platform specific information?

N/A

#### Supported testbed topology if it's a new test case?
