Fix error when compiling the Pinetime using the Docker image.
If done with Docker, the container does not trust the /sources
folder, leading to a blank response of the command that grabs
the git commit `git rev-parse --short HEAD`.
```
fatal: detected dubious ownership in repository at '/sources'
To add an exception for this directory, call:
git config --global --add safe.directory /sources
PROJECT_GIT_COMMIT_HASH_SUCCESS? 128
BUILD CONFIGURATION
-------------------
* Mode : Release
* Version : 1.3.0
* Toolchain : /opt/gcc-arm-none-eabi-10.3-2021.10
* GitRef(S) :
* NRF52 SDK : /opt/nRF5_SDK_15.3.0_59ac345
* Target device : PINETIME
* Build DFU (using adafruit-nrfutil) : Enabled
* Build resources : Enabled
```
If the `git config --global --add safe.directory /sources` is
added to the Dockerfile, the problem is solved and the hash is
added correctly.
