misc/py-anita: update to 1.48

Changes from 1.47:

When sysinst offers a choice of partitioning schemes, anita now uses
the one listed first.  Therefore, i386 and amd64 installs of versions
where sysinst offers GPT as the first choice will use GPT rather than
MBR as was previously the case.

Add support for NetBSD/hppa targets.

Support some upcoming sysinst UI changes.

The structured log file is now flushed after each line so that
it can be used to debug a hung installation without waiting for
it to time out first.

Move the automatic determination of the type of the URL argument
(e.g., distribution directory vs. installation ISO) into a new library
function anita.distribution() so that it can be used not only from the
command line but also by Python programs calling anita as a library.

When using a pre-installed image, "anita install" will now boot it to
let it resize itself, rather than postponing the resize to when the
image is later booted in another mode such as "anita test".
