[PATCH 1/7] strace: skip qual_fault-syscall.test on riscv64

[OOHehir <oo.hehir@gmail.com>]

On qemuriscv64, the strace ptest goes 283 s without output while
qual_fault-syscall.test finishes. That is 63% of the 450 s ptest-runner
limit, leaving little margin on a loaded autobuilder, so skip it there
before strace is re-enabled for riscv64.

The longest gaps between outputs in core-image-ptest-strace on
qemuriscv64 (make -j4, every output line timestamped), with the test
that ended each:

- qual_fault-syscall.test (283 s)
- filtering_syscall-syntax.test (139 s)
- trace_creds.gen.test (90 s)
- strace--tips-full.test (65 s)

The rest are under 50 s.

strace is not machine-specific, so the skip is keyed on riscv64, as the
gnutls skips in cc848c403a are. It therefore also applies to riscv64
hardware, where the test passes (VisionFive 2).
