RFR (XXS): 8025849: Redundant "pid" in VM log file name (e.g. hotspot_pidpid12345.log)

make_log_name function does the following expansion: %p => pid{pid}.
Fix VM log file name, removing unnecessary "pid" from the pattern.

FYI, I filed JDK-8025905 to track discrepancy between "%p" in LogFile & 
ErrorFile.

Best regards,
