sstate: another fix for touching files inside pseudo
This patch is a fixup for
676757f "sstate: fix touching files inside pseudo"
running the 'id' command inside the sstate_unpack_package
function shows that this funcion run inside the pseudo:
uid=0(root) gid=0(root) groups=0(root)
The check for [ -w ${SSTATE_PKG} ] and [ -O ${SSTATE_PKG}.siginfo ]
will always return true and the touch can fail when the real user
don't have permission or in readonly filesystem.
As the documentation refers:
- the file test operator "-w" check if the file has write permission
(for the user running the test).
- the file test operator "-O" check if you are owner of file
We can avoid this test running the touch and mask any return errors
that we have.
