patch.bbclass: when the patch fails show more info on the fatal error
There are situations when the user have the 'patchdir' defined
as a parameter on SRC_URI. However he doesn't know that with this
the patch is applied relatively to the receipe source dir 'S'.
- When user have 'patchdir' defined check if this directory exist.
- If the patch fails show addition info to the user:
- Import: show the striplevel
- Resolver: show the expanded 'patchdir' to the user.
The next example is from opencv in meta-oe layer, here the
patch is applied on the target directory ${WORKDIR}/git/contrib.
* When the patch fail there are no message that indicates the real reason.
patchdir=../no-found-on-file-system
ERROR: opencv-4.5.2-r0 do_patch: Command Error: 'quilt --quiltrc /build/tmp/work/core2-64-poky-linux/opencv/4.5.2-r0/recipe-sysroot-native/etc/quiltrc push' exited with 0 Output:
stdout: Applying patch 0001-sfm-link-with-Glog_LIBS.patch
can't find file to patch at input line 37
Perhaps you used the wrong -p or --strip option?
* The check of the patchdir will add a new fatal error
when the user specifies a wrong path than don't exist.

* When we can't aplly the patch but the patchdir exist,
show the expanded patchdir on fatal error.
