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.
