find-provides.ksyms, find-requires.ksyms: avoid awaking debuginfod

Starting with RHEL 9.2 and Fedora 35, debuginfod is enabled by default,
which leads to significant startup times of various tools
from the elfutils package (namely, readelf and objdump).
Unset DEBUGINFOD_URLS to avoid it.

Resolves: #2209253
