[ndctl] ndctl: fix unit test build instructions

Commit Message

Dan Williams March 9, 2016, 6:55 p.m. UTC

Use "M=tools/testing/nvdimm" from the kernel build directory rather than
"-C tools/testing/nvdimm".  This arranges for the unit test modules to
honor a "localversion" file like the one distributed by the -next tree.
Also switch from 'install' to 'modules_install' to trigger depmod to run
after the modules are installed.

    if ndctl was built with `--enable-test`.
