rlimit: rename test profiles for clarity

Add the specific rlimit command name to the filename.

Commands used to rename the files:

    git mv rlimit-bad1.profile rlimit-bad-fsize.profile
    git mv rlimit-bad2.profile rlimit-bad-nofile.profile
    git mv rlimit-bad3.profile rlimit-bad-nproc.profile
    git mv rlimit-bad4.profile rlimit-bad-sigpending.profile

Added on commit d30ae468d ("testing", 2016-11-19).
