mark rust-analyzer as a host-only tool

All tools meant to be shipped with host toolchains only should be marked
as `ONLY_HOSTS = true`, but rust-analyzer was marked as `ONLY_HOSTS =
false` incorrectly. This meant that bootstrap attempted to build
rust-analyzer for cross-compilation-only targets, causing errors because
libstd is not present on some of them.

It will still be possible to cross-compile rust-analyzer by passing a
different --host flag to ./x, like you can cross-compile other tools.
