surfaceflinger: move some libs from shared to static

These libraries are only used by this process on a device and gain no
benifit from being included as shared libraries.

Moving them to static saves disk space, memory, and cpu cycles from the
dynamic linker.

With 3 reboots before and after I'm seeing average savings of 398885 bytes of storage space from installed files, 60KB private dirty memory, 403KB PSS from libraries/binary only, and 780KB PSS from everything in showmap.
go/shared-to-static for more info on how this was determined.
