#11552 - wic: avoid unnecessary dependencies

Hi,

This patchset gets rid of building wic-tools for every image when IMAGE_FSTYPES contains 'wic'. Instead of using dependencies from wic-tools native sysroot wic expects image native sysroot to contain them. This should be done by setting WKS_FILE_DEPENDS variable in configuration files where WKS_FILE is set.

wic-tools can be used by wic when its run manually by pointing to the native sysroot using --native-sysroot option.

The patchset also contains fixes for the isoimage plugin and wic test suite breakages that were coused by the new changes.

Changes in v2:
- Fixed 2 more test cases
- Fixed default WKS_FILE_DEPENDS value (thanks to Patrick Ohly)
- Rebased on top of recent poky master

The following changes since commit f519ac010a7f7e018a83d85b6dc7778904b9a703:
