meson.eclass: Pass -Db_lto=false globally
Pass `-Db_lto=false` globally to force-disable appending `-flto`
in projects that default to it. In Gentoo, users enable LTO via setting
`*FLAGS` manually.
If a package really needs to pass `-Db_lto=true` because the build
system enables some custom logic based on it, `tc-is-lto` can be used
to determine whether LTO is enabled, and then `-Db_lto=true` can be
passed explicitly by the ebuild.
