core: Also check for a failed selftest in gpgm_data_new.

* src/data.c (_gpgme_data_new): Check for failed selftest.
* tests/run-support.h (make_filename): Print a message on mallooc
failure.
(init_gpgme_basic): New.
* tests/run-identify.c (main): Call init_gpgme_basic becuase we do not
need to setup a protocol.
* tests/t-data.c: Define PGM and include run-support.h.
(make_filename): Remove.
(main): Call init_gpgme_basic.

Note: This patch may break applications which used gpgme_data but no
gpgme_new without having called the required gpgme_check_version.

GPGME can be used without a protocol for example to work with the data
object abstraction.  Thus a call to gpgme_data_new also needs to check
the result of the core selftests - including on whether
gpgme_check_version has been called.
