Switch ClangToTLinuxASan from gyp to gn.

The other two ClangToTLinux bots are blocked on other things happening
first (ubsan tests aren't green in gn builds yet, crbug.com/606003,
and gn doesn't have linux_dump_symbols yet, crbug.com/605819)

(krasin is looking at the ubsan thing, and i'll look at linux_dump_symbols after
moving all the non-linux bots to (gyp-using) mb)

Oh sorry, I assumed it's _gyp for gyp and nothing for gn (since eventually it'll
all be gn and then _gn will be redundant, so I didn't see the point of adding
it). When I reland this I'll call it _gn.

A revert of this CL (patchset #1 id:1) has been created in
https://codereview.chromium.org/1932333002/ by thakis@chromium.org.

The reason for reverting is: ASan builds don't work in gn yet (for nacl
targets):
