Increase keymaster min_heap by 8KiB

RSA4096 key imports sometimes fail under stress testing due to a
failure to allocate a large (~16.8KiB) buffer inside of BoringSSL.
Boring needs to allocate such a large buffer to perform operations in
constant time.

Bumping the min_heap by 8KiB allows the stress test to pass.
