test: drop dlopen_gcrypt() test from test-dlopen-so

libgcrypt is used only by test-fsprg. We do not add dlopen notes for
unit tests, so the library may not be installed on the system. If systemd
is built with HAVE_GCRYPT but libgcrypt is not installed, the test fails.

There is no need to install libgcrypt solely for test-dlopen-so, so drop
the test case.
