perf record: Disable debuginfod by default
Fedora 35 sets DEBUGINFOD_URLS by default, which might lead to
unexpected stalls in perf record exit path, when we try to cache
profiled binaries.
# DEBUGINFOD_PROGRESS=1 ./perf record -a
^C[ perf record: Woken up 1 times to write data ]

Disabling DEBUGINFOD_URLS by default in perf record and adding
debuginfod option and .perfconfig variable support to enable id.
Default without debuginfo processing:
# perf record -a
Using system debuginfod setup:
# perf record -a --debuginfod
Using custom debuginfd url:
# perf record -a --debuginfod='https://evenbetterdebuginfodserver.krava'
Adding single perf_debuginfod_setup function and using
it also in perf buildid-cache command.
