perf tools: Remove unused wrapper routines

And also make xrealloc and xmalloc weak symbols so that we don't
have this problem:

 /usr/lib/gcc/x86_64-redhat-linux/4.4.1/../../../../lib64/libiberty.a(xmalloc.o):
 In function `xrealloc':
 (.text+0xc0): multiple definition of `xrealloc'
 libperf.a(wrapper.o):/home/acme_unencrypted/git/linux-2.6-tip/tools/perf/util/wrapper.c:67:
