gnuplot: upgrade 5.4.3 -> 6.0.3

This upgrade includes fixes for the following vulnerabilities:
CVE-2025-31176
CVE-2025-31178
CVE-2025-31179
CVE-2025-31180
CVE-2025-31181

This release supports qt4, qt5 and qt6 (the last one is new in this release).
There are 2 qt PACKAGECONFIGs now: qt5 and qt6 - they are mutually exclusive.

Since it is being touched, also fix lua PACKAGECONFIG, which requires lua-native
at build time.

Changelog:
