'Object code reading' test always fails on powerpc guest. Two reasons
for the failure are:

1. When elf section is too big (size beyond 'unsigned int' max value).
objdump fails to disassemble from such section. This was fixed with
commit 0f6329bd7fc ("binutils/objdump: Fix disassemble for huge elf
sections") in binutils.

2. When the sample is from hypervisor. Hypervisor symbols can not be
resolved within guest and thus thread__find_addr_map() fails for such
symbols. Fix this by ignoring hypervisor symbols in the test.
