Write output of --file-list to file in $BuildDir instead of stdout

[flxo]

The format of the --file-list output is quite nasty to handle because of two things:

• The HEADER and FILE prefixes are kind of a useless obstacle.
• The output is mixed with other bake output like this Building .... lines.

See a (stripped) example here:

...
HEADER: prebuilts/clang/linux-x86_64/arm-linux-androideabi-4.9/sysroot/usr/include/sys/types.h
HEADER: prebuilts/clang/linux-x86_64/arm-linux-androideabi-4.9/sysroot/usr/include/sys/ucontext.h
HEADER: prebuilts/clang/linux-x86_64/arm-linux-androideabi-4.9/sysroot/usr/include/sys/user.h
HEADER: prebuilts/clang/linux-x86_64/arm-linux-androideabi-4.9/sysroot/usr/include/unistd.h
**** Building 3 of 7: Mindroid.cpp (default) ****
FILE: src/mindroid/app/ContextImpl.cpp
FILE: src/mindroid/app/IOnSharedPreferenceChangeListener.cpp
FILE: src/mindroid/app/Service.cpp
FILE: src/mindroid/app/SharedPreferencesImpl.cpp
...

To make the feature more easy to use (without some grep etc processing) the output could be written to the $BuildDir. If the information about the type of a file is really needed the output could be formatted in json (like --incs-and-defs) to be more consistent.

Ok, I will write a file, makes more sense.
