pyqwt5: no longer attempting to install sip modules in /usr/share (#32)

commit 4bf4e23 eliminated configure time dependency on the "reprefix"
environment variable, but did so in such a way that sip modulues are
installed under /usr/share instead of $PYBOMBS_PREFIX/share.  This
behavior is unintended and causes an error when pybombs is executed
by a non-root user.

This commit makes the following changes:
 * mirrors the "reprefix" fix applied to the qwt5 recipe in a38e3a5
 * fixes whitespace and formatting jank introduced by the
   convert_1to2.py conversion
 * changed python module directory for sed and for installation
   from "python2.6" to "python2.7".  This _should_ be safe since
   pybombs now requires python 2.7 to run
