xmlsec: clean up the nss keywrapper part of xmlsec1-customkeymanage.patch.1

All of this is already provided by src/nss/kw_*.c. If I build xmlsec as
a shared lib, I even get linker errors due to duplicated symbols. For
some reason that does not show up in our situation where we build nss as
a static lib and link to it in xmlsecurity.
