Increase timeout from the default 20s to 100s. This test makes close to
20 million syscalls with distribution:
12327675 read
4143204 lseek
929475 close
929471 openat
92817 fstat
1431 write
...
The default timeout assumes each can finish in 1us on average which
is not true on slow machines.

* libio/tst-readline.c (TIMEOUT): Define.
This is a variant of fgets which fails with ERANGE if the
buffer is too small, and the buffer length is given as an
argument of type size_t.
This function will be useful for implementing NSS file reading
operations. Compared to a direct implementation using the public API,
it avoids an lseek system call in case the line terminator can be
found in the internal read buffer.
