python3: define a profile directory path
After ccache upgrade to 3.7.10, there comes below error when
enable ccache to build python3 and check [1] and [2] for more
details.
| Python-3.8.3/Modules/_contextvarsmodule.c:43:1: error: source locations for function 'PyInit__contextvars' have changed, the profile data may be out of date [-Werror=coverage-mismatch]
That's because the logic for profile directory changes a little in
[3] after ccache upgrades to 3.7.10.
So define a profile directory path accordingly to fix the above error.
