perf build: Fix python/perf.so library's name

Since Python 3.3 extensions have a suffix encoding platform and
version information. For example, the perf extension was previously
perf.so but now maybe perf.cpython-310-x86_64-linux-gnu.so. Compute
the extension using Python and then use this in the target name. Doing
this avoids the "perf.so" target always being rebuilt.
