package/uclibc: add custom bits/poll.h for xtensa

Browse Source 
Definitions of POLLWRNORM, POLLWRBAND and POLLREMOVE in xtensa linux
kernel are non-standard. Provide bits/poll.h with correct values for
these constants for uclibc-ng.

This fixes the following strace build errors:

  xlat/pollflags.h:75:1: note: in expansion of macro ‘static_assert’
   static_assert((POLLWRBAND) == (0x0100), "POLLWRBAND != 0x0100");
