/proc/module: fix building without kallsyms
As reported by kernelci and other build bots, we now get a link
failure without CONFIG_KALLSYMS:
module.c:(.text+0xf2c): undefined reference to `kallsyms_show_value'
This adds a dummy helper with the same name that can be used
for compilation. It's not entirely clear to me what this
should return for !CONFIG_KALLSYMS, I picked an unconditional
'false', which leads to the module address being unavailable
to user space.

Fixes: 516fb7f2e73d ("/proc/module: use the same logic as /proc/kallsyms for address exposure")
