[OE-core] [PATCH 1/2] toaster.bbclass: Fix error when toaster is used to monitor a build

[Mark Hatle]

The error being corrected looks like:

File: '/home/jenkins/workspace/OEBuild/build-32/oe-core/meta/classes/toaster.bbclass', lineno: 130, function: toaster_package_dumpdata
     0126:    lpkgdata = {}
     0127:    datadir = os.path.join(pkgdatadir, 'runtime')
     0128:
     0129:    # scan and send data for each generated package
 *** 0130:    for datafile in os.listdir(datadir):
     0131:        if not datafile.endswith('.packaged'):
     0132:            lpkgdata = _toaster_load_pkgdatafile(datadir, datafile)
     0133:            # Fire an event containing the pkg data
     0134:            bb.event.fire(bb.event.MetadataEvent("SinglePackageInfo", lpkgdata), d)
Exception: FileNotFoundError: [Errno 2] No such file or directory: '/home/jenkins/workspace/OEBuild/builds/build-32/tmp-glibc/work/core2-64-oe-linux/puzzles/2_0.0+gitAUTOINC+c6e0161dd4-r0/pkgdata/runtime'

There must be a small window before the data is available, but while the monitoring is on-going.
