[gomp4] Move libgomp plugins into subdirectory

[Julian Brown]

Hi,

This patch moves plugin-nvptx.c and plugin-host.c (from oacc-host.c)
into a new "plugin" subdirectory, as requested by Jakub, and to match
more closely the layout of the Intel MIC pieces. This also moves the
autotools bits to enable the NVPTX plugin and locate CUDA libraries
into the plugin directory's (new) configury bits.

So far this only changes the location of the source files: the plugins
themselves are still installed to the same place as before (alongside
libgomp itself).

Test results look reasonable with my (patched for PTX support) version
of the gomp4 branch. I'll apply it there shortly.

Thanks,

Julian
