print to stderr and introduce meson build script

[Prince781]

• Printing to stderr is preferable because we can separate gobject-list output from normal program output
• Introducing a Meson build script is useful for linking to gobject-list statically. It's also a more robust build system than Make.

This looks good, although I question the need to include meson here, the original goal of the raw Makefile was to reduce the dependency set as far as possible e.g. no autotools. Alternatively we should drop the Makefile to reduce duplication.
