applypatch: Fix comparison of integers of different signs.

bootable/recovery/applypatch/imgpatch.cpp:57:3: error: comparison of integers of different signs: 'unsigned int' and 'int' [-Werror,-Wsign-compare]
  CHECK_GT(expected_target_length, 0);

Test: `mmma -j bootable/recovery/applypatch` with -Wsign-compare
Test: Run recovery_unit_test on marlin.
