Fix COMPRESS/CRS MCA for C/R by returning correct value

Right now the C/R code fails because of a change introduced in
opal/mca/compress/base/compress_base_open.c and
pal/mca/crs/base/crs_base_open.c in 2013 with commit

git 734c724ff76d9bf814f3ab0396bcd9ee6fddcd1b
svn r28239

    Update OPAL frameworks to use the MCA framework system.

This commit changed a lot but also the return value of functions from
OPAL_SUCCESS to OPAL_ERR_NOT_AVAILABLE/OPAL_ERR_NOT_AVAILABLE.

This commit lets opal_compress_base_register() and opal_crs_base_open()
always return OPAL_SUCCESS and removes unneeded #includes.

This commit was SVN r30130.
