tcp: configurable source port perturb table size
On embedded systems with little memory and no relevant security concerns, it is beneficial to reduce the size of the table. Reducing the size from 2^16 to 2^8 saves 255 KiB of kernel RAM. Makes the table size configurable as an expert option. The size was previously increased from 2^8 to 2^16 in commit 4c2c8f0 ("tcp: increase source port perturb table to 2^16").
