package/libsndfile: fix c99 check

Since the bump of libsndfile to version 1.0.31 in commit
8c600fda64f48c16d20588336dd7ac6a32241c6a, the check for c99 contains
"include <wchar.h>" although the package itself does not use wchar
functions outside Windows-specific code.  This patch forces the
detection of c99 for toolchains lacking wchar.
