GHA: set `--buildinfo` for `test-torture` jobs
Only the `test-ci` build target sets `--buildinfo` automatically,
since
985f39c0ce78b546e832c250588c14023123edfb. It needs to be set
manually for other targets used in CI, such as `test-torture`,
to enable the `buildinfo.txt` dump in the runtests step.
For Test Clutch. In an attempt to re-sync `targetarch` with the rest of
macOS jobs on the feature matrix page:
https://testclutch.curl.se/static/reports/feature-matrix.html
Before this patch and possibly since the breaking update It's `aarch64e`
for torture jobs and `aarch64` for the rest
(stricly speaking `aarch64e` is the correct value for all macOS jobs, but
autotools and cmake report arm64/aarch64 without the `e`.)
Regression from
