[PATCH] test: Check for symbol ext4_dir_operations in module ext4

[eugene.loh@oracle.com]

From: Eugene Loh <eugene.loh@oracle.com>

The tst.misc.d test assumes certain kernel symbols can be found.  The
test specifies ext4`ext4_dir_operations, but there are apparently
kallmodsyms bugs that misassign the symbol to the wrong module.
Thus, the test fails to find the symbol.  Meanwhile, we are less
concerned about such older kernel bugs, since we are moving from
kallmodsyms to modules.builtin.ranges.

Modify the .x file to check for ext4_dir_operations in the ext4 module
for those cases that rely on kallmodsyms.
