Tao Bao 736d59c567 recovery: Fix the broken UI text. 
UI text is broken (doesn't show any text during FDR) due to commit
d530449e54, which reordered the calls to
RecoveryUI::SetLocale() and RecoveryUI::Init().

Because Init() uses the locale info to load the localized texts (from
images), the locale must be set prior to that via SetLocale(). This CL
refactors Init() to take the locale parameter, and removes the odd
SetLocale() API.

Bug: 34029338
Test: 'Run graphics test' under recovery.
