[OE-core] [PATCH][v2] perf: fix the install-python_ext

[rongqing.li at windriver.com]

From: Roy Li <rongqing.li at windriver.com>

1. $(grep xxx xxx) never returns 0, it maybe return empty or string, and
can not compare with 0, this fixes that python module never are installed.

2. python library is installed into /usr/lib/ by default, but we expect
it is installed into ${libdir}, so add --install-lib parameter for python
setup.py to set the library dir;
this fixes not shipped warning, since python modules are installed into
/usr/lib/, but FILE_${PN}-python expects it is under ${libdir}, which is
/usr/lib64/ for 64bit machine

3. the makefile target install-python_ext is moved from Makefile to
Makefile.perf from linux v3.13, so match install-python_ext in Makefile.*
and --root='/\$(DESTDIR_SQ)' before linux v3.13 will install the target
python library to native sysroot, so replace it with --prefix as after linux
3.13;
this fixes not shipped warning, and install target files to native dir, like
below:
