Whitelist rtld(GNU_HASH) dependency

This is needed to green-up the Linux Xenial bot [1].  rpmdeps has been updated
between Trusty and Xenial to require rtld(GNU_HASH) when the .gnu.hash section
is present in binaries.  We already ship binaries that have that section, and
glibc has supported GNU_HASH since version 2.4, so adding the new dependency
shouldn't be a problem on any systems.

Explicitly request 16.04 swarming bots for the Linux Xenial bot

There was a build step (site_per_process_webkit_layout_tests) on Linux Xenial
that for some reason was requesting Trusty swarming bots.  All of the other
steps were using Xenial bots.  This CL explicitly requests Xenial swarming bots
to fix this step.

Test removed from Network traffic annotation unittest.

Fix bad-charset-alias on Ubuntu Xenial

This is a merge of r204850 from upstream WebKit.  It is necessary to fix
bad-charset-alias.html on Ubuntu Xenial.  In the new environment, there is no
global php.ini, so we need to create one to add a default setting for charset.
