libselinux, libsemanage: make PYPREFIX computation more robust
On systems where $PYTHON is python3.5 (instead of python2 or python3),
pkg-config fails to find the Python package because it is named with a
dash (e.g. python-3.5).
Moreover the build system may have been using the pkg-config
configuration files for the wrong Python version when several Python
with the same major version number are installed (e.g. using python-3.5
on a system with both python-3.4 and python-3.5 and where
/usr/lib/pkgconfig/python3.pc is a symlink to python-3.5.pc).
In order to fix these two issues, compute $PYPREFIX from $PYTHON by
using the full major.minor version.
Moreover update Travis-Ci configuration to grab the relevant
configuration files for pkg-config from /opt/python (for example
/opt/python/3.5.2/lib/pkgconfig/python-3.5.pc) instead of using
system-provided files (/usr/lib/x86_64-linux-gnu/pkgconfig/python3.pc
and /usr/lib/x86_64-linux-gnu/pkgconfig/python2.pc).
