wf111: fix overwriting module files during install

When installing the WF111 modules, the module.* files generated during
the kernel compilation were overridden. This ended up having the wrong
information about the modules compiled in a given image (and only the
one about the WF111 module). This could be verified using the
"modprobe -l" command, with only the wf111 module showing up.

This patch fixes this by invoking the install_static target (which
will do both the build and installation) in WF111_INSTALL_TARGET_CMDS.
This way the files are not overridden but instead updated with the
additional WF111 informations.
