[U-Boot] [RFC PATCH] genboardscfg.py: use Python2 from default path

[Wolfgang Denk]

Instead of searching for Python2 in $PATH, use the one installed by
the system (i. e. /usr/bin/python2).  This prevents failures like
this:

-> ./MAKEALL m53evk
Traceback (most recent call last):
  File "tools/genboardscfg.py", line 19, in <module>
    import fnmatch
ImportError: No module named fnmatch
Failed to generate boards.cfg

This happens for example with all but the most recent versions of
Yocto based tool chains (inclusing all currently existing versions of
the ELDK), which provide a python2 binary in SYSROOT/usr/bin/python2,
but do not include the "fnmatch" module.

By using the system installed Python interpreter, the user is able to
install any missing modules himself, without need to patch and rebuild
the whole tool chain.
