[PATCH] Rename variable with confusing name

I saw this gem of not so legible code in solib-svr4.c (scan_dyntag):
if (dyn_tag == dyntag)
and thought it deserved a small rename.
This just renames variables to be a bit more clear for those who read the
code. dyn_ptr was renamed as well to keep consistency. I also constified
the parameter because, why not.
Tested only by rebuilding, since the change was done mechanically.
gdb/Changelog:
2014-08-01 Simon Marchi <simon.marchi@ericsson.com>
* solib-svr4.c (scan_dyntag): Rename dyntag, dyn_tag and
dyn_ptr variables.
