This patch adds slurmctld/controller.c and slurmd/slurmd/slurmd.c to PROC2FIX
in Makefile of the port, to fix the issue described in this report.

Environment:

    - FreeBSD: 14.3-RELEASE-p2 GENERIC (amd64) 

    - Ports tree: up to date as of 2025-08-12 

    - pkg: pkg -v -> 2.2.2


Description:
When trying to start slurmd or slurmctld they refuse to start and throw an
error. This error could be traced using truss to two files missing on PROC2FIX
in the ports Makefile.



Actual result:
: fatal: _parse_commandline: readlink failed: No such file or directory


Expected result:
slurmctld and slurmd start up fine.


Analysis:
I was able to trace the error down to src/slurmctld/controller.c and
src/slurmd/slurmd/slurmd.c. These two files were the ones still expecting a
linux procfs under /proc, which i could easily fix via adding these two the
ports PROC2FIX.


Proposed fix:
diff --git a/sysutils/slurm-wlm/Makefile b/sysutils/slurm-wlm/Makefile

Workarounds for users (until fixed):
Either manually edit the Makefile, or mount linprocfs under /proc (not
recommended, may brake other applications)
