pam_time: use vendor specific time.conf as fallback
Use the vendor directory defined by --enable-vendordir=DIR configure
option as fallback for the distribution provided default config file
if there is no configuration in /etc.
* modules/pam_time/pam_time.8.xml: Describe this.
* modules/pam_time/time.h [VENDOR_SCONFIGDIR] (VENDOR_PAM_TIME_CONF):
New macro.
* modules/pam_time/pam_time.c (_pam_parse) [VENDOR_PAM_TIME_CONF]:
Try to open VENDOR_PAM_TIME_CONF file when no conffile= option was
specified and PAM_TIME_CONF file does not exist.
