Update lock pattern types for android 11
The stored id for the different types of the lock pattern was chnaged
with Android 11. You can find the updated list in the LockPatternUtils:
https://android.googlesource.com/platform/frameworks/base/+/refs/tags/android-11.0.0_r25/core/java/com/android/internal/widget/LockPatternUtils.java#113
It was changed in 5e891bcc04556a3595ab349381acc2a2e36a69d1:

The old CREDENTIAL_TYPE_PASSWORD_OR_PIN was essentialy split in
CREDENTIAL_TYPE_PASSWORD and CREDENTIAL_TYPE_PASSWORD_OR_PIN.
This code updates the matching in twrp, so that the correct unlocking
method for file base decryption can be found. Without these changes twrp
always try to use the default password and obviously fails. With these
changes the usual password dialog is shown and the decryption is
successfully.
