gh-133741: Check strace version in support.strace_helper

[vstinner]

Need strace 5.5 or newer for the --trace option.

• Issue: test_fileio fails if strace version is too old #133741

[vstinner]

Python 3.13 test_subprocess uses a different strategy: it runs strace on the /bin/true program to check if strace works.

My PR parses the strace version from strace -V output.

Could the version check go inside _can_strace (https://github.com/python/cpython/pull/133763/files#diff-f46934bbb48e17e6a386e49dd7375e2e5542c5d529bcadae34f3bb1e3575d3b5R203-R210). That already does a cache variable. Definitely like the approach of just disable on older strace versions.
