[yocto] [meta-cgl][PATCH v2] poky-cgl: avoid installing multiple syslogs

[jackie.huang at windriver.com]

From: Jackie Huang <jackie.huang at windriver.com>

do_rootfs fails if multiple syslogs are installed:
| Error: package syslog-ng-3.8.1-r0.i586 conflicts with sysklogd provided
  by sysklogd-1.5.1-r0.i586

core-image-cgl requires packagegroup-core-full-cmdline which depends
on VIRTUAL-RUNTIME_syslog (default to sysklogd), so set the
VIRTUAL-RUNTIME_syslog in distro conf and no need to depends
on any syslog in packagegroup-cgl-applications, then we ensure
that only one syslog is installed to avoid conflicts.
