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 4c2c8f03a5ab ("tcp: increase source port perturb table to
2^16").
