Eduard Zingerman 42597aa372 libbpf: Hashmap.h update to fix build issues using LLVM14 
A fix for the LLVM compilation error while building bpftool.
Replaces the expression:

  _Static_assert((p) == NULL || ...)

by expression:

  _Static_assert((__builtin_constant_p((p)) ? (p) == NULL : 0) || ...)

When "p" is not a constant the former is not considered to be a
constant expression by LLVM 14.

The error was introduced in the following patch-set: [1].
The error was reported here: [2].
