perf probe: Add '--demangle'/'--no-demangle'

You can't pass demangled name into "perf probe", because of special chars:
./perf probe -f -x /tmp/a.out 'foo(int)'
Semantic error :There is non-digit char in line number.

And you can't even pass without demangling (because it search symbol in
DSO with demangle=true):
./perf probe -f -x /tmp/a.out _Z3fooi
no symbols found in /tmp/a.out, maybe install a debug package?

However:
nm /tmp/a.out | grep foo
000000000040056d T _Z3fooi

After this patch, using the next command:
./perf probe -f --no-demangle -x /tmp/a.out _Z3fooi

probe will be successfully added.
