[Buildroot] [PATCH v2 1/1] trace-cmd: use pkg-config instead of python-config

trace-cmd use python-config to find out which headers
and libraries should be used to link against the Python libraries.
By default, python-config returns paths that are inappropriate for
cross-compilation.
This patch replaces python-config with pkg-config as a workaround.
Fixes:

Note: I'll add python3 support latter.
v1: rework python dependency
add host-swig dependency
disable python support if python package is not selected
v0: initial review
