[RFC PATCH v4 22/37] arm64: kernel: Skip validation of kuser32.o

[Chen Zhongjin]

From: Raphael Gault <raphael.gault@xxxxxxx>

kuser32 being used for compatibility, it contains a32 instructions
which are not recognised by objtool when trying to analyse arm64
object files. Thus, we add an exception to skip validation on this
particular file.
