Link dependencies dynamically

An attempt to add feature flags to the widevine service
(b/311951236) caused a memory regression (b/324438957).
Using the static library for feature flags results
in SIGSEGV due to possible clobbering of static libraries
(b/311951236 comment18).

An alternate option is to make libcutils and libc++ shared
