RFR: 8239365: ProcessBuilder/Basic.java test has trouble on AIX sometimes

[Adam Farley8]

Hi All,

Reviews and sponsor requested for a small test change.

Parts of the test appear to be pattern-matching on error messages from 
catalogues on the system.

When an AIX machine has the file set "bos.msg.en_US.rte", the messages are 
different for the same codes.

E.g. for Error code 13 (in the relevant group, see libc.cat) we get:

*With* file set: error=13, The file access permissions do not allow the 
specified action
*Without* file set: error=13, Permission denied

Since the pattern the test matches on is "Permission denied", it fails if 
the aforementioned file set is installed.

The simplest option appears to be adding the second potential form of the 
message into the regex (see webrev).

Another option is to have "error=x," replace the regex for each error 
message, unless the format of this changes on an OS I haven't checked.
