unixPB: Install Fedora devkit with GCC14 for riscv64

[sxa]

This could be aligned with the main JDK head and use GCC 13.2 but since riscv64 development is constantly advancing we are prototyping with GCC14 for now.

I've tested using th build dockerfile and it correctly installs teh F28 devkit with this PR.

Looks good.

Just a note - adding the devkit makes the images size about double what it was previously:

Rebuild of the build image got a bit messy:

• CentOS7/x64 and CentOS7/ppc64le both had a failure in the make-4.1 download: "Request failed: <urlopen error ('_ssl.c:602: The handshake operation timed out',)>", "url": "https://ftp.gnu.org/gnu/make/make-4.1.tar.gz"} link.
• For CentOS6/x64 it gave a similar error for autoconf: 802.5 fatal: [localhost]: FAILED! => {"changed": false, "dest": "/tmp/autoconf-2.69.tar.gz", "msg": "Request failed: <urlopen error _ssl.c:477: The handshake operation timed out>", "state": "absent", "url": "https://ftp.gnu.org/gnu/autoconf/autoconf-2.69.tar.gz"}

Noting that this failed on the centos7_build_updater and the new ghcr.io job at build_image_updater. Linux/aarch64 was not affected in either case. Since these did not fail on the last attempt I'm going to put it down to a random network glitch and run the updater job again ...
