gnupg: disable tests to avoid running target binaries at build time

By default, the tests are built and run at do_compile and we can see
errors like below in log.do_compile:

  gnupg-2.4.4/tests/cms/inittests: line 99: ../../sm/gpgsm: cannot execute binary file: Exec format error

Note that the do_compile process still succeeds. However, we'd better avoid
executing these target binaries at build time.
