    stapdyn: Resolve the target executable from the PATH
    
    BPatch::processCreate needs a full path for the process argument, so we
    need to walk the PATH to figure that out.  We already did this in
    dynsdt, but using a private function.  Now both use find_executable from
    util.h, in a new form that doesn't care about sysroots.
    
    * util.cxx (find_executable): Add a name-only version that just wraps
      the full sysroot version, for convenience.  Also let a few more things
      be const in the implementation.
    * hash.cxx (get_base_hash): Use the wrapper function for finding gcc,
      instead of having a "dummy" sysenv itself.
    * stapdyn/stapdyn.cxx (main): Resolve the target with find_executable.
    * stapdyn/dynsdt.cxx (resolve_path): Removed.
      (main): Use find_executable instead.
