Hojun-Cho f6477cb97d test: the unit build takes the dialect the daemon is built with ...

9c compiles with -std=gnu11 and UNIT_CFLAGS overrode that with -std=c99,
so the tests built the daemon's own sources under a dialect the daemon
never sees.  Under it glibc hides lstat, and server_test.c reaches
<sys/stat.h> before srv.c pulls in u.h -- it must, since thread.h
defines recv as chanrecv and the socket recv it calls has to be declared
first.  So make all was green while make check would not compile.
HOST_CFLAGS keeps -std=c99: those are host programs with no Plan 9
headers.
