LU-4124 build: make module installation directory flexible

Add --with-kmp-moddir option to configure.

Distributions vary in the installation directory for kernel modules.

The RHEL standard installation directory is
        /lib/modules/$(uname -r)/extra
while the SLES standard is
        /lib/modules/$(uname -r)/updates

Adding the option --with-kmp-moddir option to configure allows users
to select the appropriate installation target.  With this change, it
is neccessary to support both options in the test framework.
