relocate broken with python 3.12.8

[nyanloutre]

The CVE-2024-9287 fix included in python 3.12.8 is breaking the relocate feature.

python 3.12.6 activation script:

# on Windows, a path can contain colons and backslashes and has to be converted:
if [ "${OSTYPE:-}" = "cygwin" ] || [ "${OSTYPE:-}" = "msys" ] ; then
    # transform D:\path\to\venv to /d/path/to/venv on MSYS
    # and to /cygdrive/d/path/to/venv on Cygwin
    export VIRTUAL_ENV=$(cygpath "/tmp/tmp.INbM468TTf")
else
    # use the path as-is
    export VIRTUAL_ENV="/tmp/tmp.INbM468TTf"
fi

python 3.12.8 activation script:

# on Windows, a path can contain colons and backslashes and has to be converted:
if [ "${OSTYPE:-}" = "cygwin" ] || [ "${OSTYPE:-}" = "msys" ] ; then
    # transform D:\path\to\venv to /d/path/to/venv on MSYS
    # and to /cygdrive/d/path/to/venv on Cygwin
    export VIRTUAL_ENV=$(cygpath /tmp/tmp.INbM468TTf)
else
    # use the path as-is
    export VIRTUAL_ENV=/tmp/tmp.INbM468TTf
fi

The quotes are gone and seems to break the regex.
The regex will now match $(cygpath /tmp/tmp.INbM468TTf) instead of /tmp/tmp.INbM468TTf because it does not contains quotes anymore.
