travis: Enable rust-analysis package for more targets

This commit enables the `rust-analysis` package to be produced for all targets
that are part of the `dist-*` suite of docker images on Travis. Currently
these packages are showing up with `available = false` in the
`channel-rust-nightly.toml` manifest where we'd prefer to have them show up for
all targets.

Unfortunately rustup isn't handling the `available = false` section well right
now, so this should also inadvertently fix the nightly regression.
