Subject: gnu: meson: Introduce versioned 'meson-0.60' variable.

While at it, change inheritance such that newest comes first.

* gnu/packages/build-tools.scm (meson-0.63): Move to the top.
(meson-0.60): Inherit from MESON-0.63.
(meson-0.59): Inherit from MESON-0.60.  Don't use PACKAGE/INHERIT.
(meson): Turn into alias for MESON-0.60.
