[meson] Remove `default_library=both` from `default_options`.
It is inconsistent with what all other Meson projects do.
It also prevents static linking to FreeType when it is a subproject because
`default_options` in a subproject takes precedence on values set on the main
project. For example, building 'GStreamer' with `-Ddefault_library=static`
would still dynamically link on FreeType unless the user also sets
`-Dfreetype2:default_library=static`.
* meson.build: Updated.
* .gitlab-ci.yml: Retain `both` option for testing.
