chromeos-chrome: add -no-rosegment when using lld.

Without this flag, binaries linked with lld contains three PT_LOAD
segments whereas our symbolizer (breakpad) expects only one PT_LOAD
segment. This CL fixes that.

BUG= chromium:851642 
TEST=only one PT_LOAD segment is seen in the generated binary.

This bug has an owner, thus, it's been triaged. Changing status to "assigned".

dump_syms works on unstripped binary on both AMD64 and ARM boards.
on stripped binary, 
dump_syms segfaults on AMD64 and it works fine on ARM boards.

We may migrate the linker to lld on ARM board first.

dump_sys does not segfault if we remove the -no-rosegment flag from LLD.
