[Taler] Building libeufin-0.9.4a-sources.tar.gz

[Slack Coder]

Hi,

There is an error when building libeufin from the release sources.  It expects to be built from within a git repository:

```

For more details see https://docs.gradle.org/8.6/release-notes.html

Starting a Gradle Daemon (subsequent builds will be faster)

> Configure project :
fatal: not a git repository (or any of the parent directories): .git

```

Below is a quick patch for those who want to compile from this source's source.

```
