[OE-core] [PATCH 0/1] Avoid race in perform_groupmems()

[Peter Kjellerstedt]

We have seen sporadic failures in our CI builds due to useradd,
groupadd or groupmems failing. I have now tracked it down to
perform_groupmems() in useradd_base.bbclass, where I found code to
temporarily create the /etc/gshadow file in the sysroot if it did not
exist. Purportedly this was due to groupmems requiring the gshadow
file to exist. There are, however, no real evidence of that
requirement, and actually creating and removing the file the way it is
currently done WILL cause failures when one task removes it while
another task expects it to already exist.
