Infer nightly feature on nightly toolchain
Before this commit, enabling procmacro2_semver_exempt would disable
wrap_proc_macro, meaning that real spans would not be preserved by proc
macros. One would also need to enable the "nightly" feature in order to
preserve spans when using procmacro2_semver_exempt.
This commit automatically enables wrap_proc_macro when building with
procmacro2_semver_exempt on a nightly compiler.
