RFR: 8367034: [REDO] Protect ExecuteWithLog from running with redirection without a subshell

[Magnus Ihse Bursie]

This is a redo of [JDK-8233115](https://bugs.openjdk.org/browse/JDK-8233115). The problem was that some of the AOT test command lines had `,` in them. Since this is interpreted as argument separator by make, it is not allowed, and it should be escaped to `$(COMMA)`. 

However, it seems like the GNU make parser did not consider `,` to be an argument parser if it was nested inside matching `(` ... `)`, and so by pure luck it worked anyway, until I removed those subshell parentheses.
