Subject: [PATCH] perf, map:  Don't try to find DSOs in SYSV maps

We are seeing a lot of the following with regards to SYSV memory

Failed to open /SYSV0000279c, continuing without symbols

We don't believe this memory will have DSO info, so treat it like the heap and
stack for now and skip it to prevent the warning.
