audit: allow other filter list types for AUDIT_EXE
This patch removes the restriction of the AUDIT_EXE field to only
SYSCALL filter and teaches audit_filter to recognize this field.
This makes it possible to write rule lists such as:
auditctl -a exit,always [some general rule]
# Filter out events with executable name /bin/exe1 or /bin/exe2:
auditctl -a exclude,always -F exe=/bin/exe1
auditctl -a exclude,always -F exe=/bin/exe2
