perf annotate: Use capstone_init and remove open_capstone_handle from disasm.c

capstone_init is made availbale for all archs to use and updated to
enable support for CS_ARCH_PPC as well. Patch removes
open_capstone_handle and uses capstone_init in all the places.

Committer notes:

Avoid including capstone/capstone.h from print_insn.h to not break the
build in builtin-script.c due to the namespace clash with libbpf:

  /usr/include/capstone/bpf.h:94:14: error: 'bpf_insn' defined as wrong kind of tag
