[Bug libc/2703] New: envz_strip() works incorrectly

["Joy dot lists at gmail dot com" <sourceware-bugzilla at sourceware dot org>]

The envz_strip () routine in the string/envz.c works incorrectly.

In my opinion after strip "arg1=value1\0arg2\0arg3=value3\0arg4\0" it should
return "arg1=value1\0arg3=value3\0", however, it returns "arg1=value1\0".

After my investigation, I think it is caused by 
  "memmove (entry + entry_len, entry, left);"
which should be
  "memmove (entry, entry + entry_len, left);"
