Ron Yorston 6ad38d66d0 libbb: code shrink fgets_str ...

Use a NULL value of maxsz_p to indicate to xmalloc_fgets_internal()
that the caller doesn't care about the maximum size of the buffer.
This allows the default maximum size to be set once in
xmalloc_fgets_internal() instead of separately in each caller.
