Fix deterministic build

[luzius1089]

Fixes: #152

The GingerCommon project missed some configurations to ensure deterministic builds. For example:

For example, one typical diff after disassembly:

Logger.Log("Exception from " + GetType().Name, ex, LogLevel.Warning, "C:\\Users\\Neo\\Documents\\work\\GingerPrivacy\\GingerWallet\\GingerCommon\\Providers\\ExchangeRateProviders\\ExchangeRateProvider.cs", "GetSupportedCurrenciesAsync", 55);

Logger.Log("Exception from " + GetType().Name, ex, LogLevel.Warning, "C:\\Users\\Neo\\Documents\\work\\GingerPrivacy\\GingerWalletClone\\GingerCommon\\Providers\\ExchangeRateProviders\\ExchangeRateProvider.cs", "GetSupportedCurrenciesAsync", 55);

[CallerFilePath] inserts the filepath compile time into the binary, <PathMap> ensures to insert the same path.

After the fix, all the files were identical.
