There are more places where we'll need to add it later, when Go 1.18
comes out with support for it in the "net" package. Also, allowedips
still uses slices internally, which might be suboptimal.

The existing test would occasionally flake out with:
--- FAIL: TestRatelimiter (0.12s)
ratelimiter_test.go:99: Test failed for 127.0.0.1 , on: 7 ( not having refilled enough ) expected: false got: true
FAIL
FAIL golang.zx2c4.com/wireguard/ratelimiter 0.171s
The fake clock also means the tests run much faster, so
testing this package with -count=1000 now takes < 100ms.
While here, several style cleanups. The most significant one
is unembeding the sync.Mutex fields in the rate limiter objects.
Embedded as they were, the lock methods were accessible
outside the ratelimiter package. As they aren't needed externally,
keep them internal to make them easier to reason about.
Passes `go test -race -count=10000 ./ratelimiter`

Mathias should probably add his copyright headers to each file too.
