It is not used by spice-common, but both server and client can use it.
Compared to current checks in spice-gtk and spice server this macro only
supports libsasl2.

v3: - removed unused AM_CONDITIONAL
v2: - only supports libsasl2
- PKG_CHECK_MODULES is used instead of AC_CHECK_LIB and AC_CHECK_HEADER
