qt5: qtwebengine: reduce parallel make jobs 

The aim is to reduce even more the memory used by the host at build time
to avoid the OOM killer killing the linker.

Otherwise it can fail in machines with few memory even though the linker
is configured with '--no-keep-memory'.

Notice that we also reduce the parallel jobs expanded by 'ninja' build
system configuring and exporting NINJAFLAGS variable. Otherwise this
build system does not honor PARALLEL_MAKE variable.

Fix:
  arm-dey-linux-gnueabi-g++: internal compiler error: Killed (program cc1plus)
  ninja: build stopped: subcommand failed.
