8372710: Update ProcessBuilder/Basic regex

[rudraroop]

Hi,

This is a backport of JDK-8372710: Update ProcessBuilder/Basic regex

Original patch applies cleanly to jdk25u-dev

Reasoning -

The format for IOException was changed in JDK-8352533. This format change was made in openjdk25u-dev, but not updated in this test.

Background -

Originally, the fix was made in ibmruntimes/openj9-openjdk-jdk25#40 done by @theresa-m as IBM's AIX relies on this format. It was then contributed to openJDK by @Harshit470250 in JDK-8372710
