```
std.event.WaitGroup: fix compilation (acquire->lock, release->unlock)

In 008b0ec5e58fc7e31f3b989868a7d1ea4df3f41d the `std.Thread.Mutex` API was changed
from `acquire` and `release` to `lock` and `unlock`. `std.event.Lock` still uses `acquire`
and `release`. `std.event.WaitGroup` is using `std.Thread.Mutex` and was not updated to use
`lock` and `unlock`, and so compilation failed prior to this commit.
