Message:

Expand WebContent process sandbox with additional syscall
​https://bugs.webkit.org/show_bug.cgi?id=206260
<rdar://problem/58580997>

Reviewed by Per Arne Vollan.

Testing shows that we will improve performance on some platforms by supporting an additional Syscall.

This patch revises our sandboxes so that WebKit can use this fast path if available.

No new tests. No change in test result behavior.
