posix: remove unneeded option to link with posix subsys

The CONFIG_APP_LINK_WITH_POSIX_SUBSYS option was originally present so that internal POSIX implementation headers would be on the include path. There is no implicit need for any app or library to include private POSIX headers. Instead, the standard POSIX API should be used.
