meson: Fix check for cairo and cairo-ft dependencies 

When cairo comes from a subproject fallback it should still take
cairo-ft dependency, otherwise it miss freetype2 cflags.

Also update wrap file to use upstream repository now that meson support
has been merged.

This requires Meson >= 0.54.0 because cairo itself requires that version
and we use the new `fallback: 'cairo'` syntax without specifying a
variable name because cairo does not provide a variable name for
cairo-ft.
