perf scripting perl: Ignore some warnings to keep building with perl headers
On gcc 12 we started seeing this:

So disable those warnings to keep building with perl devel headers.
Noticed, among other distros, on opensuse tumbleweed:
gcc version 12.1.1 20220629 [revision 7811663964aa7e31c3939b859bbfa2e16919639f] (SUSE Linux)
