libc-wasi/posix.c: Fix POLL{RD,WR}NORM in uClibc (#2069)

Browse Source 
POLLRDNORM/POLLWRNORM may be not defined in uClibc, so replace them
with the equivalent POLLIN/POLLOUT.

Refer to https://www.man7.org/linux/man-pages/man2/poll.2.html
  POLLRDNORM Equivalent to POLLIN
  POLLWRNORM Equivalent to POLLOUT
