wic: exec_native_cmd: implement support for pseudo
Wic runs some tools through pseudo, which makes exec_native_cmd
to fail and throw cryptic error message when tool is not baked:
For example:
Error: exec_cmd: 'export
PSEUDO_PREFIX=/media/ssd/poky-build/tmp/sysroots/x86_64-linux/usr;export
PSEUDO_LOCALSTATEDIR=/media/ssd/poky-build/tmp/work/qemux86-poky-linux/
...
PSEUDO_PASSWD=/media/ssd/poky-build/tmp/work/qemux86-poky-linux/ ...
PSEUDO_NOSYMLINKEXP=1;/media/ssd/poky-build/tmp/sysroots/ ...
mkfs.ext4 -F -i 8192 /var/tmp/wic/build/rootfs_platform.7.ext4 -L
platform -d
/media/ssd/poky-build/tmp/work/qemux86-poky-linux/core-image-minimal/...
returned '1' instead of 0
Made exec_native_cmd aware of pseudo and properly report
errors when command is not found.
