Update usage and readme for zipalign.
Added the "-c" flag to the README, and added a short description of the
flag meanings to the usage output. Threw in an AOSP copyright one-liner
for good measure.

zipalign -- zip archive alignment tool
usage: zipalign [-f] [-v] <align> infile.zip outfile.zip
+ zipalign -c [-v] <align> infile.zip
+ -c : check alignment only (does not modify file)
-f : overwrite existing outfile.zip
-v : verbose output
<align> is in bytes, e.g. "4" provides 32-bit alignment

By default, zipalign will not overwrite an existing output file. With the
"-f" flag, an existing file will be overwritten.
+You can use the "-c" flag to test whether a zip archive is properly aligned.
