[PATCH v9 09/13] mips: select HAVE_SECCOMP_FILTER and provide seccomp_execve

[Will Drewry <wad@chromium.org>]

Facilitate the use of CONFIG_SECCOMP_FILTER by wrapping compatibility
system call numbering for execve and selecting HAVE_SECCOMP_FILTER.

v9: rebase on to bccaeafd7c117acee36e90d37c7e05c19be9e7bf
