t/no-mmap-inval: Replace `valloc()` with `t_posix_memalign()`

Address the limitations of valloc(). This function, which is primarily
used for allocating page-aligned memory, is not only absent in some
systems but is also marked as obsolete according to the `man 3 valloc`.

Replace valloc() with t_posix_memalign() to fix the following build
error:

  no-mmap-inval.c:28:56: warning: call to undeclared function 'valloc'; ISO C99 and \
  later do not support implicit function declarations [-Wimplicit-function-declaration]
          p.cq_off.user_addr = (unsigned long long) (uintptr_t) valloc(8192);
                                                                ^
