scripting engine
A brown paper bag where -Wno-error=deprecated-declarations was added
from compiler output when the right thing is to add
-Wno-deprecated-declarations, fix it.
Fixes: 4ee3c4da8b1b9c22 ("perf scripting python: Do not build fail on deprecation warnings")

First noticed with fedora:rawhide:
48 11.10 fedora:rawhide : FAIL gcc version 12.1.1 20220628 (Red Hat 12.1.1-3) (GCC)
util/scripting-engines/trace-event-python.c: In function 'python_start_script':
util/scripting-engines/trace-event-python.c:1899:9: error: 'PySys_SetArgv' is deprecated [-Werror=deprecated-declarations]
1899 | PySys_SetArgv(argc + 1, command_line);
No time now to address this warning, so don't make it an error, in time
we should either add yet more ifdefs to continue supporting older
systems or just convert to whatever new infra python put in place for
argv processing, sigh.

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:

Rename build libperf to perf, because it's used to build perf.
The libperf build object name will be used for libperf library.

cc1: all warnings being treated as errors
After digging perl5 repository, I find out that we will meet this
compile error with perl from v5.21.1 to v5.25.4

Move the scripts objects building under build framework to be included
in the libperf build object.
