Address the warnings in recovery code
The following warnngs generate when compile with WITH_TIDY=1
.../bootable/recovery/applypatch/imgdiff.cpp:968:7: warning: 'src_ranges' used after it was moved [bugprone-use-after-move]
src_ranges.Clear();
^
.../bootable/recovery/applypatch/imgdiff.cpp:966:27: note: move occurred here
split_src_ranges->push_back(std::move(src_ranges));
The logic itself seems correct since the class is meant to be cleared
after move. I feel the std::move in 966 is actually useful to call the
move constructor in RangeSet. So I just modify L968 to suppress the
warning.
Less important ones:
bootable/recovery/applypatch/applypatch_modes.cpp:79:34: warning: passing result of std::move() as a const reference argument; no move will actually happen [performance-move-const-arg]

bootable/recovery/updater/include/private/commands.h:310:16: warning: std::move of the variable 'patch' of the trivially-copyable type 'PatchInfo' has no effect; remove std::move() [performance-move-const-arg]
bootable/recovery/updater/install.cpp:663:43: warning: passing result of std::move() as a const reference argument; no move will actually happen [performance-move-const-arg]
