build: fix fs.copyfile usage for meson versions 0.64/0.64.1
Though this function was introduced in 0.64, its usage with install_dir
was broken till meson version 1.0.0. Hence, bump the minimal required
meson version for the fs.copyfile()
routine.
See the following meson commit for details: https://github.com/mesonbuild/meson/commit/100456de0761ee949e2277c97746cb8571b6ba39
