Andre Heider 7379f8bd3e build: prereq: drop support for Python 3.5
The final Python 3.5 release was 3.5.10 in September 2020 [0].
This release series is now End-of-Life (EOL).

The only LTS distribution that still only ships Python 3.5 is Ubuntu 16.04,
which will be EOL in April 2021 [1].

The meson build system bumped their python requirement to 3.6 for the 0.57.0
release. This patch ensures that OpenWrt can update meson while still
relying on the host python.
