cyrus-sasl: fix parallel build issue

While building plugins, each <plugin>.c requires a <plugin>_init.c,
and the <plugin>_init.c is dynamically generated by makeinit.sh.

But the makeinit.sh generates all *_init.c (13 mechanism plugins,
3 auxprop plugins) at one time, if there are multiple plugins,
there will be multiple makeinit.sh invoking.

It caused a parallel issue, the *_init.c files will be generated
repeatedly.

It occasionally generate dapdb_init.c incorrectly
[snip plugins/ldapdb_init.c]
SASL_CANONUSER_PLUG_INIT( ldapdb )
SASL_CANONUSER_PLUG_INIT( ldapdb )
SASL_CANONUSER_PLUG_INIT( ldapdb )
[snip plugins/ldapdb_init.c]

Let makeinit.sh generate the expected <plugin>_init.c which
is exactly required by <plugin>.c.
