perf test java symbol: Remove needless debuginfod queries
Test case 'Test java symbol' might run for a long time. On Fedora 38 the
run time is very, very long:
Output before:
# time ./perf test 108
108: Test java symbol : Ok
real 22m15.775s
user 3m42.584s
sys 4m30.685s
#
The reason is a lookup for the server for debug symbols as shown in:
# cat /etc/debuginfod/elfutils.urls
https://debuginfod.fedoraproject.org/
#
This lookup is done for every symbol/sample, so about 3500 lookups
will take place.
To omit this lookup, which is not needed, unset environment variable
DEBUGINFOD_URLS=''.
Output after:
# time ./perf test 108
108: Test java symbol : Ok
real 0m6.242s
user 0m4.982s
sys 0m3.243s
