[PATCH] tests: skip ENOSPC injection on restricted systems

[PATCH] tests: skip ENOSPC injection on restricted systems

[Eric Wong]

Yama will not allow ptrace(2) on existing processes (only new
ones) if the kernel.yaml.ptrace_scope sysctl is non-zero.  Skip
those tests for now since the majority of strace(1) testing
is probably done on systems without ptrace restrictions.
