mbedtls: Make imported version tag more verbose

Patater · Patater · commit bb17408a14a1 · 2019-05-23T14:47:42.000+01:00
When importing development releases of Mbed TLS into Mbed OS, it is
useful to be able to know a the particular git commit hash that was
imported. This change avoids ever creating a VERSION.txt for Mbed TLS
containing only "development", which is fairly useless since one doesn't
know where the development branch was at the time of import.
