ninfod: Fix meson warning about 'install' arg in 'configure_file'

We claim to support 0.39, but install: argument in configure_file was
introduced in version 0.50. This produces the following meson warning:

WARNING: Project specifies a minimum meson_version '>=0.39' but uses features which were added in newer versions:
 * 0.50.0: {'install arg in configure_file'}

From the doc for the install argument [1]:
" When omitted it (install) defaults to true when install_dir is set and
not empty, false otherwise."

Therefore remove install: argument and just depend on install_dir for installing.
