Library order is important because it is used to construct class loader
context, which is then written into OAT/ODEX files and chacked against
class loader context constructed by PackageManager on the device. If the
orders are different, dexpreopted code is rejected.
This CL fixes a few problems that caused reordering:
- 'filter' function arguments are swapped so that patterns list comes
first, and the library list second
- JSON representation of class loader context is changed to avoid
unmarshaling it to Go maps, which may reorder keys
- library list is no longer sorted (it's unclear why it was sorted)

Test: lunch cf_x86_64_phone-userdebug && m && launch_cvd \
adb wait-for-device && adb root && adb logcat \
| grep -E 'ClassLoaderContext [a-z ]+ mismatch'
# empty grep output, no errors
