[PATCH 1/3] libtracefs utest: Silence string-plus-int warnings

[Ian Rogers <irogers@xxxxxxxxxx>]

Fix warnings of the form:

utest/tracefs-utest.c:476:35: error: adding 'int' to a string does not append to the string [-Werror,-Wstring-plus-int]
        CU_TEST(strstr(kprobes, KPROBE_1 + 2) != NULL);
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~
