build: Bump required meson version

And remove the "install" arg in configure_file() to quiet the warnings

WARNING: Project specifies a minimum meson_version '>= 0.47.0' but uses features which were added in newer versions:
 * 0.49.0: {'/ with string arguments'}
 * 0.50.0: {'install arg in configure_file'}
