lib: Remove redundant ftrace flag removal
Since architectures can implement ftrace using a variety of mechanisms, generic code should always use CC_FLAGS_FTRACE rather than assuming that ftrace is built using -pg. Since commit: 2464a609ded09420 ("ftrace: do not trace library functions") ... lib/Makefile has removed CC_FLAGS_FTRACE from KBUILD_CFLAGS, so ftrace is disabled for all files under lib/. Given that, we shouldn't explicitly remove -pg when building lib/string.o, as this is redundant and bad form. Clean things up accordingly. There should be no functional change as a result of this patch.
