[Buildroot] [PATCH 2/2] package/libplist: fix python support

[Yann E. MORIN <yann.morin.1998@free.fr>]

Samuel, All,

> - fixes the python3 support detection in the libplist CMake code;
> - correctly sets the dependencies and configure options in libplist.mk.

Rather than trying to fix a 3-year old release (1.6), can't we have a look at
bumping to the latest release, 1.11, which is 'only' 6-month old?

I'll give it a spin.

Regards,
Yann E. MORIN.
