exportfs: Properly parse IPv6 literal strings with null termination
The original implementation was using strncpy() with a truncation
length to an uninitialized stack buffer, leaving a string that
was only null terminated by luck.
While here, change to use no-copy semantics (no extra buffer) to
avoid buffer overflows altogether. exportfs already modifies argv
contents elsewhere, so this doesn't break anything anew.
Fixes: 4663c648 (exportfs: Support raw IPv6 addresses with
"client:/path")
