perf symbols: Support minimal build without libelf
Now we have isolated all ELF-specific stuff, it's possible to build without libelf. The output binary can do most of jobs but lacks (user level) symbol information - kernel symbols are still accessable thanks to the kallsyms. To build perf without libelf (elfutils), give NO_LIBELF=1 to make. For now, only 'perf probe' command is removed since it depends on libelf/libdw heavily.
