Subject: [PATCH] sysctl: increase max supported line length of the conf file

I ran into this limit with net.ipv4.ip_local_reserved_ports ,
sysctl complained about the line after the long line, further
slowing down my error hunting.

Due to fgets usage, increase buffer size to 4096 chars with
minimum amount of code changes.
