cp: Rename -d option to -P

Browse Source 
The -d option is a GNU extension and is equivalent to its "-P
--preserve=links" options.

Since we don't implement the --preserve=links functionality anyway (it
means preserve hard links between files), just call it -P, which is
specified by POSIX.

Additionally, there is no need to check for cp_Pflag again before
copying the symlink itself because the only way the mode in the stat
will indicate a symlink is if we used lstat (which we only do if -P is
specified).
