Trim leading and trailing whitespace from stored CSP headers.

Trim leading and trailing whitespace from stored CSP headers.

mikispag@ noticed in [1] that we're adding whitespace to the original
policy when processing multiple headers. This patch strips whitespace,
which means we're storing less data, and sending what developers
expect to see in the violation reports.
