Quagga: Fix alignment in netlink messages in some cases
The alignment of nlmsg_len is calculated wrong leading to wrong rta_len
calculations for nested TLVs when the data length of the last TLV added
to the nested TLV is not aligned to RTA_ALIGNTO already. Use same fix
that was implemented in iproute2 by Thomas Graf circa 2005. A reference
to the fix is at

Ticket: CM-6491
Reviewed By: CCR-3087
Testing Done: MPLS testing with other patches in SE-1
Note: Prior to MPLS, we didn't face this problem as we haven't really had
any nested TLVs; even if RTA_MULTIPATH were to be considered a nested TLV,
it didn't have any non-aligned fields.
