deps(PNG): Always _only_ build shared libs

Trying to get to the bottom of why OIIO is continuing to link system shared system PNG (CI images) instead of freshly-built static libs. Presumably, if I build shared PNG libs, OIIO will prefer the newer ones over the system libraries. (Which I guess would mean any found dynamic libraries are preferred over any found static libraries...) Signed-off-by: Zach Lewis <[email protected]>
