Brad Fitzpatrick cb0208161f tailcfg: bump CurrentMapRequestVersion, forgotten earlier
In f45a9e291b (2021-03-04), I tried to bump CurrentMapRequestVersion
to 12 but only documented the meaning of 12 but forgot to actually
increase it from 11.

Mapver 11 was added in ea49b1e811 (2021-03-03).

Fix this in its own commit so we can cherry-pick it to the 1.6 release
branch.

(cherry picked from commit 4145bb71487a45b899b6a1b06d9a27963c795e45)
