go.mod: bump looprpc and swapserverrpc

[starius]

Fix the build if GOPROXY="direct":

lightning-terminal$ go mod tidy 
go: downloading github.com/lightninglabs/loop/looprpc v1.0.2
go: downloading github.com/lightninglabs/loop/swapserverrpc v1.0.11
verifying github.com/lightninglabs/loop/[email protected]/go.mod: checksum mismatch
        downloaded: h1:+hPlWT2LGxEUY9mMVB2FcbV3KJmd1cmEezmZQagVUtY=
        go.sum:     h1:w6zur9qV9EBY7I7bpnUYp0QGjVqNl9cjnozpPal9/XY=

SECURITY ERROR
This download does NOT match an earlier download recorded in go.sum.
The bits may have been replaced on the origin server, or an attacker may
have intercepted the download attempt.

For more information, see 'go help module-auth'.

This happened, because the tags were reassigned to another commit and proxy.golang.org cached an old version.

New tags point to the same state.
