Since fd9e5ef7b7 ("libsepol: use constant keys in hashtab functions")
it is possible to call hashtab_search() with a const char* key value.
Doing so fixes compiler warnings about non-const char* string literals
(-Wwrite-strings flag).

When running "make test" with the Address Sanitizer (by adding
-fsanitize=address to compiler flags), a lot of memory leaks are
reported from checkpolicy. Anyway some leaks come from the tests and it
seems cleaner to start fixing these ones.

When compiling libsepol tests, clang complains about some uninitialized
variables:
test-common.c:171:14: error: variable 'my_primary' is used
uninitialized whenever 'if' condition is false
[-Werror,-Wsometimes-uninitialized]
} else if (my_flavor == TYPE_ALIAS) {

test-common.c:179:30: note: uninitialized use occurs here
CU_ASSERT(type->primary == my_primary);

} else if (my_flavor == TYPE_ALIAS) {

This is because the call to CU_FAIL("not an alias") is not fatal in
test_alias_datum(), and variables my_primary and my_value are indeed
used uninitialized in a CU_ASSERT statement later.
Silent the warning by moving the elseif condition to a CU_ASSERT
statement which replaces the CU_FAIL.

Even though g_b_role_2 is used both in
tests/policies/test-linker/small-base.conf and
tests/policies/test-linker/module1.conf, it seems to only exists in the
scope of the base policy.
This fixes the following failure of "make -C libsepol test":

This test must have been disabled a very long time ago, before attributes were present in the kernel policy. Since the attributes are now present this unit test should be turned back on, unless I'm missing something pretty major (it looks reasonable and is successful when run).
