BUILD: Fix variable substitution in cwrap.m4

Add another dollar sign to have variable name substituted by m4 in
"cwrap.m4" further substituted with its value by shell in "configure".

Before, this:

    [ test x$2 = xyes]

would produce this in "configure" for uid_wrapper test:

     test xHAVE_UID_WRAPPER = xyes

which is always false.

Now the changed code:

    [ test x$$2 = xyes]

Would produce this in "configure" instead:

    test x$HAVE_UID_WRAPPER = xyes

which will properly process the test result.

This fixes uid_wrapper and nss_wrapper detection, which were considered
missing otherwise, resulting in cwrap tests not running.
