python,python3: honour the SOURCE_DATE_EPOCH for the build-info

The Modules/getbuildinfo.c allows the use of DATE and TIME
macros to be defined via CFLAGS.

These vars, control the build date & time when the
interpreter is opened, and can be read via the
`platform._sys_version()` function.

So, a conversion from SOURCE_DATE_EPOCH to DATE & TIME
is required at build-time.

This is especially needed for `platform._sys_version()`
to work.
The installation of pip seems to rely on this.

The logic has been adapted from:
