Remove no longer provided onepin-opensc-pkcs11.so. Add iasecc-tool, openpgp-tool and sc-hsm-tool.
Removed BR libtool-ltdl-devel to build with glibc's libdl instead.
Removed and obsoleted mozilla-opensc-signer and opensc-devel subpackages; dropped patches which are now upstreamed. It is no longer possible to build in both pcsc-lite and openct support, so opensc now gets built exclusively with pcsc-lite.
