[PATCH] python3: customize the python interpreter for nativesdk

["Yu, Mingli" <mingli.yu@windriver.com>]

From: Mingli Yu <mingli.yu@windriver.com>

Make sure the python interpreter is "#!/usr/bin/env python3" for
nativesdk to avoid the shebang path exceeding the limit when install
the sdk under the directory with long path.

Before:
 $ cd ${target_sdk_dir}
 $ vi ./sysroots/x86_64-oesdk-linux/usr/bin/2to3
 #!${target_sdk_dir}/sysroots/${SDK_SYS}/usr/bin/python3.9
 [snip]

After:
 $ cd ${target_sdk_dir}
 $ vi ./sysroots/x86_64-oesdk-linux/usr/bin/2to3
 #!/usr/bin/env python3
 [snip]
