src: error reporting with -f and read from stdin
Reading from stdin requires to store the ruleset in a buffer so error
reporting works accordingly, eg.
# cat ruleset.nft | nft -f -
/dev/stdin:3:13-13: Error: unknown identifier 'x'
ip saddr $x
^
The error reporting infrastructure performs a fseek() on the file
descriptor which does not work in this case since the data from the
descriptor has been already consumed.
This patch adds a new stdin input descriptor to perform this special
handling which consists on re-routing this request through the buffer
functions.
Fixes: 935f82e7dd49 ("Support 'nft -f -' to read from stdin")
