ltp: set PREFERRED_PROVIDER and rename runtests_noltp.sh script
* ltp installs 2 different runtests_noltp.sh files from different
directories into /opt/ltp/testcases/bin/runtests_noltp.sh
last one installed wins and causes unexpected changes in
buildhistory's files-in-image.txt report, rename them to have
unique name as other ltp scripts have.
* also define PREFERRED_PROVIDER to resolve note shown when
building with meta-oe layer:
NOTE: multiple providers are available for ltp (ltp, ltp-ddt)
NOTE: consider defining a PREFERRED_PROVIDER entry to match ltp
