[PATCH 2/3] man/man7/pipe.7: Note kernel commit of the soft limit triggered cap increase

7543e84442d7 did reference the kernel commit in its commit
message, but the convention to include it in the man page
source as well is helpful to wider audience.

Fixes: 7543e84442d7 ("pipe.7: Document change to default pipe size when soft limit is exceeded")
