[OE-core] [PATCH] perf: Additional fixes for 5.5+

[Joel Stanley]

In e5c4f3127521 ("perf: fix build for v5.5+") this recipe was fixed for
5.5 kernels, however testing shows that there's a few other changes
required.

perf's build system uses a file from the scripts/ directory to
generate a bpf header, so this must be added to the list of files to
perform a replace on.

Additionally the replacement would run on all occurrences of
/usr/bin/python first, resulting in lines that contained
"/usr/bin/env python32". This re-orders the sed lines to avoid that.

This fixes warnings such the following:

   File "/usr/lib/python3.6/sysconfig.py", line 421, in _init_posix
     _temp = __import__(name, globals(), locals(), ['build_time_vars'], 0)
 ModuleNotFoundError: No module named '_sysconfigdata'

Found when attempting to use 5.5 with OpenBMC.

The sed method of fixing this may be fragile, and moving to patching the
source tree may be preferred in the future.
