build: standardize ./configure arguments

For consistency and to make it clearer where jobs differ (for example,
to see where `--enable-analyzer` is used).

Changes:

* Always use --prefix=/usr and --enable-fatal-warnings (except in the
  Alpine job due to current warnings; see #6224)
* Use the same argument order

Note: mkdeb.sh and platform/rpm/mkrpm.sh already pass `--prefix=/usr` to
./configure.
