Use RSP file for soong_zip in target_files.zip

target_files.zip passes a list of files to soong_zip in a file list
file, which soong_zip interprets as a glob.  Adding a file called "["
causes soong_zip to error with "syntax error in pattern".  Use an RSP
file instead, which after I1de7829c668538204fc4a2ac793a4f88dbc886c9
does not interpret entries as globs.

soong_zip: don't glob RSP file entries

File arguments are considered globs, but RSP file entries should be
considered filenames without globbing.  Escape RSP file entries so
they don't get treated as globs later.
