LOG: [libunwind] include alloca.h in test/aarch64_za_unwind.pass.cpp (#207376)

Glibc provides the alloca function as a part of stdlib.h when
_GNU_SOURCE is declared (which is the case with standard linux builds).
[1]

On non-glibc systems, this may not be the case (for example, picolibc).
These libraries may not implicitly include alloca.h as a part of the
standard lib.
