[PATCH AUTOSEL for 4.14 141/161] selftests/ftrace: Add some missing glob checks

[Sasha Levin]

From: "Steven Rostedt (VMware)" 

[ Upstream commit 97fe22adf33f06519bfdf7dad33bcd562e366c8f ]

Al Viro discovered a bug in the glob ftrace filtering code where "*a*b" is
treated the same as "a*b", and functions that would be selected by "*a*b"
but not "a*b" are not selected with "*a*b".

Add tests for patterns "*a*b" and "a*b*" to the glob selftest.
