[Buildroot] [PATCH 1/1] libqrencode: select libpng only when tools are selected

[Danomi Manchego <danomimanchego123@gmail.com>]

As stated on the libqrencode web site, PNG (or SDL) is only
needed for the test and utility programs; the library itself
has no dependencies.

While we are here, remove spaces in the ifeq clause, to match
the examples in the buildroot manual.
