adb: log more detail on failure to read keys.
Before we just got "Failed to read key". After:
adb E 10-07 08:20:14 258249 258249 auth.cpp:176] Failed to read key \
from '/usr/local/google/home/enh/.android/adbkey'
94390117965240:error:0900006e:PEM routines:OPENSSL_internal:NO_START_LINE:\
external/boringssl/src/crypto/pem/pem_lib.c:622:Expecting: ANY PRIVATE KEY
Also fix the misleading "Failed to generate" message from adb_auth_init.
Bug: http://b/141715453
Test: manually corrupted key; see above
