[SPARK-33045][SQL][FOLLOWUP] Fix build failure with Scala 2.13

[sunchao]

What changes were proposed in this pull request?

Explicitly convert scala.collection.mutable.Buffer to Seq. In Scala 2.13 Seq is an alias of scala.collection.immutable.Seq instead of scala.collection.Seq.

Why are the changes needed?

Without the change build with Scala 2.13 fails with the following:

[error] /home/runner/work/spark/spark/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/parser/AstBuilder.scala:1417:41: type mismatch;
[error]  found   : scala.collection.mutable.Buffer[org.apache.spark.unsafe.types.UTF8String]
[error]  required: Seq[org.apache.spark.unsafe.types.UTF8String]
[error]                 case null => LikeAll(e, patterns)
[error]                                         ^
