perf(init): don't fork scutil when $HOST is already the Bonjour name

On macOS `scutil --get LocalHostName` was run on every startup to get a
stable short hostname for the zcompdump filename. When $HOST is the
Bonjour name (`<LocalHostName>.local`), which is the common case, the
LocalHostName is just $HOST without the suffix, so use that directly and
keep the scutil lookup for hosts that got a different name from DHCP.

Measured on macOS arm64, zsh 5.9: 6 ms -> 0.2 ms per interactive start.
