Subject: [PATCH 335/341] test: support MPOL_LOCAL matching in unpatched strace
 versions

The MPOL_LOCAL constant is not recognized in current strace versions.
Let's match at least the numerical value of this constant until the
strace patch is approved & merged.

(cherry picked from commit ac14396d027023e1be910327989cb422cb2f6724)
