libsemanage/tests: fix linking

When -lbz2 is written before libsemanage.a in the linker command line,
the linker may fail to find all needed symbols. This occurs for example
when building on Ubuntu 14.04 without the gold linker (cf. Travis build
result https://travis-ci.org/fishilico/selinux/builds/245072498):

    gcc libsemanage-tests.o test_semanage_store.o test_utilities.o utilities.o
    -L/home/travis/build/fishilico/selinux/installdir/usr/lib -o libsemanage-tests
    -lcunit -lbz2 -laudit ../src/libsemanage.a -lselinux -lsepol
    ../src/libsemanage.a(direct_api.o): In function `bzip':
    direct_api.c:(.text+0xee6): undefined reference to `BZ2_bzWriteOpen'
    direct_api.c:(.text+0xf11): undefined reference to `BZ2_bzWriteClose'
    direct_api.c:(.text+0xf79): undefined reference to `BZ2_bzWrite'
    direct_api.c:(.text+0xfa1): undefined reference to `BZ2_bzWriteClose'
    direct_api.c:(.text+0xfe0): undefined reference to `BZ2_bzWriteClose'
    ../src/libsemanage.a(direct_api.o): In function `bunzip':
    direct_api.c:(.text+0x114e): undefined reference to `BZ2_bzReadOpen'
    direct_api.c:(.text+0x1249): undefined reference to `BZ2_bzRead'
    direct_api.c:(.text+0x13b4): undefined reference to `BZ2_bzReadClose'
    ../src/libsemanage.a(seusers_local.o): In function `semanage_seuser_audit':
    seusers_local.c:(.text+0x4c5): undefined reference to `audit_open'
    seusers_local.c:(.text+0x5b6): undefined reference to `audit_log_semanage_message'
    seusers_local.c:(.text+0x5cd): undefined reference to `audit_close'

As ../src/libsemanage.a is a dependency of $(EXECUTABLE) in the
Makefile, use $^ to include it in the command line. While at it, put $^
after $(LDFLAGS) as other Makefiles do.
