pp_ctl.c - copy hook into %INC not alias it
When an @INC hook is executed and it updates %INC it can result in @INC
being updated and the hook being destroyed.
This seems to be because the SV fetched from @INC is stored into %INC
directly, essentially creating an alias (in perl terms) of the original.
When the alias is updated, for instance by setting it to be a string,
this is reflected in both @INC and %INC.
By copying the sv before we store it we avoid this problem.
We can't run the test under miniperl as it uses IO layers.
This should fix GH #20577.
