Typo in globus_gsi_system_config.c

[fscheiner]

Detected by chance. There is a superfluous comma here:

gct/gsi/sysconfig/source/library/globus_gsi_system_config.c

Lines 1901 to 1910 in aed61cc

	if(user_key && !(*user_key))
	{
	GLOBUS_GSI_SYSCONFIG_ERROR_RESULT(
	result,
	GLOBUS_GSI_SYSCONFIG_ERROR_GETTING_KEY_STRING,
	(_GSSL("The user key could not be found in:\n,"
	"1) env. var. X509_USER_KEY\n"
	"2) $HOME/.globus/userkey.pem\n"
	"3) $HOME/.globus/usercred.p12\n\n")));
	goto done;

...that is not present for the case when the cert file is missing:

.globus/userkey.pem missing, .globus/usercert.pem present
