BIP155: clarify that "services" uses CompactSize
The Bitcoin Core source code has `VARINT` type which is different than
the "variable integer" format used all over the P2P protocol and also
for the "services" field in this BIP. The latter is called `CompactSize`
in some BIPs and also in the Bitcoin Core source code, thus use the word
`CompactSize` to refer to it and link to its documentation.
