Subject: [PATCH] [version] fix `OPENTHREAD_BUILD_DATETIME` in version string
 (#7398)

If `OPENTHREAD_BUILD_DATETIME` is defined by the build system, the
version string would be something like:

OPENTHREAD/20191113-03303-gbdeacdc55-dirty; NRF52840DK-engFeb 08 2022 13:05:38
                                                         ^^

We shouldn't put the separator in the macro, but put it in the version
string instead.
