Add missing call to adjustUuid in FrameworkMediaDrm

Browse Source 
Before API 27, the platform DRM components incorrectly expected
`C.COMMON_PSSH_UUID` instead of `C.CLEARKEY_UUID` in order to perform
ClearKey decryption. `FrameworkMediaDrm` is responsible for doing this
adjustment on these API levels, but this call was missed when
refactoring some DRM code in
c872af4bc0.

This led to `MediaCodec$CryptoException: Operation not supported in this
configuration` errors when doing ClearKey playback on devices with
API < 27. This was because the earlier, clearer error from the
`MediaCrypto` constructor was being swallowed and transformed to
`requiresSecureDecoder = true` by the `catch` logic in
`FrameworkMediaDrm.requiresSecureDecoder`.

This change also makes the error handling in
`FrameworkMediaDrm.requiresSecureDecoder` more robust by assuming
`requiresSecure = false` for ClearKey (and true for all other DRM
schemes), since we know that ClearKey never supports secure decoding.
This will help avoid more ClearKey playback failures if we see other,
unrelated, errors at this point.
