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.
