Handle grep finds no matches.
Bazel is more strict about exit codes in genrules. In
vendor.mime.types.minimized, there are no no-empty lines, so the grep
fails. Update the command to succeed even though grep fails.
Test: m mimemap and verify contents of
out/soong/.intermediates/frameworks/base/mime/vendor.mime.types.minimized/android_common/gen/vendor.mime.types
