CI: Disable optimizations in "minimal" build tests (#1278)

Our "minimal" layer tests had to stop disabling optimizations in 2019
commit 4f3c41b due to problems specific to GCC v9 (v9.1 or earlier). GCC
v9.4 (and later) appear to work OK (at least on Ubuntu 22.04), so let's
try to resume testing --disable-optimizations ./configure option.
