sys-devel/binutils: make gprofng optional (masked USE flag)

We can enable this by default in future, but it's brand new
in 2.39 with several bugs:
- Doesn't build on musl (https://sourceware.org/bugzilla/show_bug.cgi?id=29477)
- No man pages (https://sourceware.org/bugzilla/show_bug.cgi?id=29521)
- Broken at runtime without Java (https://sourceware.org/bugzilla/show_bug.cgi?id=29479)
- binutils-config (and this ebuild?) needs adaptation first (https://bugs.gentoo.org/865113)
