sstate.bbclass: catch ValueError from incorrectly written sstate manifests
* in some rare cases the file format might be broken, e.g. when you run
out of disk space while writing to it (hint: make sure to use
BB_DISKMON_DIRS on _all_ the builds, to make sure that they can stop
gracefully before this happens).
* will show error like this:
ERROR: Invalid line '/OE/build/luneos-thud/webos-ports' in sstate manifest '/OE/build/luneos-thud/webos-ports/tmp-glibc/sstate-control/index-allarch'
when the file isn't complete, like in my case:
$ tail -n 2 /OE/build/luneos-thud/webos-ports/tmp-glibc/sstate-control/index-allarch
/OE/build/luneos-thud/webos-ports/tmp-glibc/stamps/all-webos-linux/org.webosports.app.calculator/0.1.1+gitrAUTOINC+
9e9eb67c28-r0 /OE/build/luneos-thud/webos-ports/tmp-glibc/sstate-control/manifest-allarch-org.webosports.app.calculator /OE/build/luneos-thud/webos-ports/tmp-glibc/work/all-webos-linux/org.webosports.app.calculator/0.1.1+gitrAUTOINC+
9e9eb67c28-r0
/OE/build/luneos-thud/webos-ports
* instead of much longer exception which doesn't really show what's
wrong to selectively fix that (other than removing while TMPDIR):
ERROR: Command execution failed: Traceback (most recent call last):
