AK+LibC: Remove SERENITY_LIBC_BUILD guard around `<initializer_list>`

This was required before commit 5f724b6ca1aae3a5a8c7189069649e8a9347cca2
when we were building LibC before libstdc++ headers were available in
the sysroot. However as noted in that commit, we never actually needed
to be building LibC before libstdc++, so we can go ahead and remove this
ancient hack.
