Bug 5489: Fix "make check" linking on Solaris (#2049)

Change link order of libcomm and libip to fix missing symbols at link
time on Solaris:

    libtool: link: /usr/gcc/14/bin/g++ ... -o tests/testCacheManager
    _ZN2Ip11InterceptorE ... libcomm.a
    _ZN2Ip9Intercept9LookupNatERKN4Comm10ConnectionE ... libcomm.a
    ld: fatal: symbol referencing errors
