Remove redundant checks for MSG_* from configure.ac
It is redundant to check for the presence of MSG_NOSIGNAL macro in
configure.ac, define HAVE_MSG_NOSIGNAL and then check whether the later
is defined in the source code. Instead we can check directly whether
MSG_NOSIGNAL is defined. Same for MSG_DONTWAIT.
In addition to that, the checks we had in configure.ac produce a
compiler warning about unused variable and thus could fail if
-Werror is present and erroneously proclaim that the macros are
not available.
