build: Skip PK-specific tests if algo is disabled
* configure.ac: Define AM_CONDITIONALs for USE_DSA, USE_RSA, USE_ELGAMAL, USE_ECC so Makefiles can depend on them. * tests/Makefile.am: Skip tests that test only one public key algorithm if that algorithm is disabled.
Skip building and running tests that are specific for a public key
algorithm if that algorithm was disabled using the
--enable-pubkey-ciphers configure option.
