fix: replace bare except with except BaseException in utils.py

[harshadkhetpal]

Summary

Replace bare except: with except BaseException: in skcuda/utils.py.

Bare except: catches all exceptions including KeyboardInterrupt, SystemExit, and GeneratorExit. Since this block immediately re-raises a RuntimeError, except BaseException: is the correct replacement — it preserves interrupt semantics while making the intent explicit.

Change:

# Before
try:
    p = subprocess.Popen(cmds, stdout=subprocess.PIPE, ...)
    out = p.communicate()[0].decode()
except:
    raise RuntimeError('error executing {0}'.format(cmds))

# After
try:
    p = subprocess.Popen(cmds, stdout=subprocess.PIPE, ...)
    out = p.communicate()[0].decode()
except BaseException:
    raise RuntimeError('error executing {0}'.format(cmds))

Testing

No behavior change for normal exception paths — correctness fix only.
