libproc: Match prefixes when looking up mapped object by name.
When looking up an object by name, allow prefix matches if no direct match is found. This allows one to, for example, match libc entry probes with: # dtrace -n 'pid$target:libc.so::entry' -c ./foo instead of requiring "libc.so.7" or a glob. Also remove proc_obj2map() as it currently just duplicates the functionality of proc_name2map(). It's supposed to take a Solaris link-map ID as a paramter, but support for this isn't implemented and isn't required to support DTrace's pid provider.
