BTF testsuite: Remove explicit check on btm_type

Browse Source 
The value of btm_type is the BTF type ID of the referred type.  The order in
which the BTF types are added can change across platforms and also as the code
evolves, hence changing the BTF type ID. As there is no direct and portable
method of testing that a BTF type refers to another BTF type of a specific
kind, remove the explicit check on btm_type.

This patch adjusts the testcase without affecting the test coverage as other
testcases already have similar constructs. It also fixes a subset of failures
as seen on Darwin.
