Backport of #78958 to release/7.0

Customer Impact
When building a self-contained console application targeting .NET 7, the console application doesn't work with shebang in Linux. This causes powershell v7.3.0 to stop working with shebang on Linux.
When building the same console application targeting .NET 6, the produced console application works fine with shebang.
Testing
CI coreclr and libraries tests
Risk
Low, the change just swaps the order of means we use for getting the current executable path, the
/proc/self/exeis used first now. And in 6.0, we accidentally were using just the/proc/self/exefor some time, so it was well tested.
