RR(S): JDK-8025812 tmtools/jmap/heap_config tests fail on Linux-ia32 because it 'Can't attach to the core file'

[Dmitry Samersoff]

Hi Everybody,

Please review the fix

http://cr.openjdk.java.net/~dsamersoff/JDK-8025812/webrev.01/

The value of p_memsz filed of elf header of LOAD section inside coredump
is rounded up to page size. So round up corresponding value read from
the header of library it self.
