tools: Handle seq num for BGP as-path in frr-reload.py

If frr.conf has bgp as-path access-list clause without sequence number
then upon performing frr-rleoad, the running config clause with sequence
number will always be deleted and the new ones without sequence will
be re-added.
This could lead to blackholing until the config gets reapplied.

Testing:

frr.conf:
bgp as-path access-list important_internet_bgp_as_numbers permit _16509_

Running config:
bgp as-path access-list important_internet_bgp_as_numbers seq 5 permit
_16509_
!

Before fix
Upon frr-reload it deletes and readd line as without seq

2024-04-26 03:16:45,772  INFO: Executed "no bgp as-path access-list
important_internet_bgp_as_numbers seq 5 permit _16509_"

'bgp as-path access-list important_internet_bgp_as_numbers permit
_16509_\n'

After fix:
no form is not executed and no delta determine between frr.conf
and running-config.
