Initialize reglocs for VMCOREINFO
MSan complains:
Uninitialized value was created by an allocation of 'reglocs' in the stack frame
#0 0x562d35c686f0 in handle_core_note elfutils/src/readelf.c:12674:3

#colno = handle_core_registers (ebl, ebl->elf, desc + regs_offset,
# reglocs, nregloc);
Strictly speaking, this is not a problem, because nregloc == 0, but for
other note types we initialize it anyway, so do it here as well.
