perf build: Install libsymbol locally when building

The perf build currently has a '-Itools/lib' on the CC command
line. This causes issues as the libapi, libsubcmd, libtraceevent,
libbpf and libsymbol headers are all found via this path, making it
impossible to override include behavior.

Change the libsymbol build mirroring the libbpf, libsubcmd, libapi,
libperf and libtraceevent build, so that it is installed in a directory
along with its headers.

A later change will modify the include behavior.  Don't build kallsyms.o
as part of util as this will lead to duplicate definitions. Add
kallsym's directory to the MANIFEST rather than individual files, so
that the Build and Makefile are added to a source tar ball.
