This allows to use install-wrap when the source scripts is in a
subdirectory.

Doesn't work when build-time python path differs from install-time. Do
we care about this given tools should be packaged/built for the
specific run-time distro?

The Xen tools contain a number of Python extensions written in C. The
C API to Python, used by these extensions, is not stable from one
version of Python to the next.
Our build system uses whatever version of Python is the default on the
build system at that time to build these extensions. However, the
actual scripts such as `xm' use #!/usr/bin/env python which uses
whichever version of Python is the default on the deployment system at
the time of invocation.
If for any reason these two versions of Python are not the same (eg,
because the system is built on one computer and executed on another,
or because the system's gains a more recent Python installation
alongside the original which changes the previous default), warnings
and failures occur.
In this patch I arrange for Python scripts to be installed via a
special wrapper around `install', which determines the build-time
Python version and path and then writes that into the #! line at the
point of `make install' (or `make dist'). (It can also be overridden
by setting PYTHON_PATH.)
