m4: Add macro for --with-sasl

Browse Source 
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.

# SPICE_CHECK_SASL
# ----------------
# Adds a --with-sasl switch to allow using SASL for authentication.
# Checks whether the required library is available. If it is present,
# it will return the flags to use in SASL_CFLAGS and SASL_LIBS variables,
# and it will define a have_sasl configure variable and a HAVE_SASL preprocessor
# symbol.
# ----------------
