Allow portage_sandbox_t ptrace capabilities

During installation of system packages like python, ustr, ... the portage_sandbox_t domain requires ptrace capabilities.

If not allowed, the following error is returned:

/sbin/ldconfig -n /var/tmp/portage/dev-libs/ustr-1.0.4-r1/image//usr/lib64
ISE:_do_ptrace ^[[0mptrace(PTRACE_TRACEME, ..., 0x0000000000000000, 0x0000000000000000): Permission denied /usr/lib/libsandbox.so(+0x3812)[0x7535af0ca812] /usr/lib/libsandbox.so(+0x38a3)[0x7535af0ca8a3] /usr/lib/libsandbox.so(+0x5595)[0x7535af0cc595] /usr/lib/libsandbox.so(+0x5a87)[0x7535af0cca87] /usr/lib/libsandbox.so(+0x68de)[0x7535af0cd8de] /usr/lib/libsandbox.so(execvp+0x6c)[0x7535af0ceb3c]

This seems to be during a standard "make install" of the package but part of Portage' sandbox usage (above error for ustr, but packages like python exhibit the same problem.)
