memblock tests: fix undefined reference to `panic'

[ Upstream commit e0f5a8e74be88f2476e58b25d3b49a9521bdc4ec ]

commit e96c6b8f212a ("memblock: report failures when memblock_can_resize
is not set") introduced the usage of panic, which is not defined in
memblock test.

Let's define it directly in panic.h to fix it.
