swtpm_setup: Initialize variables to avoid compiler warnings

Fix issue #591 by initializing the variables swtpm_has_tpm2 and
swtpm_has_tpm12.

swtpm_setup.c:1178:31: note: 'swtpm_has_tpm2' was declared here
     gboolean swtpm_has_tpm12, swtpm_has_tpm2;
                               ^~~~~~~~~~~~~~
swtpm_setup.c:1019:5: error: 'swtpm_has_tpm12' may be used uninitialized in this function [-Werror=maybe-uninitialized]
     printf("{ \"type\": \"swtpm_setup\", "
     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
            "\"features\": [ %s%s\"cmdarg-keyfile-fd\", \"cmdarg-pwdfile-fd\", \"tpm12-not-need-root\""
