Python GDB support may use Python 2 or 3.
Inferior.read_memory() may return a 'buffer' with Python 2 or a
'memoryview' with Python 3 (see also
https://sourceware.org/gdb/onlinedocs/gdb/Inferiors-In-Python.html)
The elf.add_vmcoreinfo_note() method expects a "bytes" object. Wrap
the returned memory with bytes(), which works with both 'memoryview'
and 'buffer'.
Fixes a regression introduced with commit
d23bfa91b7789534d16ede6cb7d925bfac3f3c4c ("add vmcoreinfo").
