Resolve Java 21 ftbfs

This MR resolves 1057680.

Note: this MR depends on the fix of general ftbfs 1042314, and a fix to gettext 1056293

Changes:

• Remove fips target from the build. It is safe to do, as fips-compatible version can not be built from source, as it requires binaries of the FIPS provider (e.g. Bouncycastle FIPS jars).

Testing:

• prepared chroots by installing Ubuntu version of jruby otherwise the build will fail due to 1042314 and gettext due to 1056293
• rebuilt in sid chroot
• rebuilt in Java 21 default sid chroot
