LibCore: Remove unnecessary lifetime extension from ProcessSpawnOptions

Browse source 
We don't need `file_actions` to be a constant-reference. It's created
in-place by its one user (HackStudio). Because it is currently a const-
ref, if we try to create a ProcessSpawnOptions like so:

    Core::ProcessSpawnOptions options { .name = "foo"sv };

We get the following error with clang 18:

    lifetime extension of temporary created by aggregate initialization
    using a default member initializer is not yet supported; lifetime of
    temporary will end at the end of the full-expression
