WebRTC+libyuv: switch to use_allocator GYP variable.

WebRTC+libyuv: switch to use_allocator GYP variable.

Use of linux_use_tcmalloc=0 is about to be deprecated and
should be replace with use_allocator=none.
See https://groups.google.com/a/chromium.org/forum/#!topic/chromium-dev/2BONW-Xd19c/discussion
for more info.

This CL also removes pointless use of this variable for Mac
and a no-longer-needed use of GYP_GENERATORS=ninja.

BUG=345554
TEST=local Mac and Linux builds passing.

lgtm, though heads up that the release_extra_cflags are different in some
places.

File masters/master.client.webrtc.fyi/master_linux_cfg.py (right):

https://codereview.chromium.org/218493009/diff/1/masters/master.client.webrtc...
masters/master.client.webrtc.fyi/master_linux_cfg.py:54:
'release_extra_cflags="-gline-tables-only"'),
This is different than the others, which are just -g.

Same here

Thanks. I looked into the details and changed all to use -g.

I think it's actually better for us to use -g here as well, since that generate
complete debug information.

This line was originally copied from the Chromium versions of these bots, which
uses -gline-tables-only to generate debug line-information only (needed for
stack traces). 
I remember reading that they don't use -g since their codebase is so large. For
WebRTC, I don't think it'll be a problem.
