Subject: tests: skip tests if strace is not functional
X-Git-Url: https://gitweb.ps.run/ps-cgit/commitdiff_plain/ca98c9e7bf31617efc3ff7d3575efe5bba3cde1a?hp=ca98c9e7bf31617efc3ff7d3575efe5bba3cde1a

tests: skip tests if strace is not functional

Chances are that strace is available but not functional due to
restricted permissions:

strace: test_ptrace_get_syscall_info: PTRACE_TRACEME: Operation not permitted
strace: ptrace(PTRACE_TRACEME, ...): Operation not permitted
+++ exited with 1 +++

Just skip the tests then.
