setuptools3-base.bbclass: override default subprocess timeout

The environment variable SETUPTOOLS_SCM_SUBPROCESS_TIMEOUT allows to override
the subprocess timeout. The default is 40 seconds and should work for most
needs.[1] However, it was not enough while using git shallow tarball and starting
multiple Yocto world builds in one host.

|   File "tmp/work/x86_64-linux/python3-scancode-native/32.1.0/recipe-sysroot-
native/usr/lib/python3.13/subprocess.py", line 1263, in _check_timeout
|     raise TimeoutExpired(
|     ...<2 lines>...
|             stderr=b''.join(stderr_seq) if stderr_seq else None)
| subprocess.TimeoutExpired: Command '['git', '--git-dir', 'tmp/work/x86_64-
linux/python3-scancode-native/32.1.0/git/.git', 'status', '--porcelain',
'--untracked-files=no']' timed out after 40 seconds

Explicitly set variable SETUPTOOLS_SCM_SUBPROCESS_TIMEOUT to 600s in bbclass,
and we could override it in local.conf
