taskdata.py: include more information in error message about broken task depends

This is what was reported when variable expansion in the 'depends'
varflag of a task was broken:

   ERROR: Error for .../refkit-image-common.bb, dependency ${@ does not contain exactly one ':' character.
    Task 'depends' should be specified in the form 'packagename:task'

It's not clear which task had this broken 'depends' and while one can
guess that variable expansion failed, the full expression isn't
printed either.

This is more useful:

   ERROR: Error for .../refkit-image-common.bb:do_stage_swupd_inputs[depends], dependency ${@ in '      virtual/fakeroot-native:do_populate_sysroot     ${@ ' '.join(['bundle-refkit-image-common-%s:do_swupd_list_bundle' % x for x in '${SWUPD_BUNDLES}'.split()]) } ' does not contain exactly one ':' character.
    Task 'depends' should be specified in the form 'packagename:task'

The 'depends' part gets repeated intentionally, to ensure that it doesn't get overlooked.
