test/CMakeLists.txt: bumped CTest timeout to accommodate macos-* runner slowness

[firewave]

The macos-* runners are much slower than the other leading to sporadic timeouts when running CTest with a debug build in the CI.

[firewave]

5/107 Test  #15: TestCondition ........................***Timeout  90.07 sec
[...]
6/107 Test  #68: TestTokenizer ........................***Timeout  90.04 sec

The same test on from the same workflow on ubuntu-22.04:

6/107 Test  #15: TestCondition ........................   Passed   32.07 sec
[...]
5/107 Test  #68: TestTokenizer ........................   Passed   26.92 sec

Most of the time in tests is spent because of copying the settings (actually it is copying the Library within). This will be addressed in the future in the prerequisite work towards automatic library detection within the application.

I removed the timeout to get the actual runtime but the test finished in the expected amount of time:

5/107 Test  #15: TestCondition ........................   Passed   24.06 sec
6/107 Test  #68: TestTokenizer ........................   Passed   25.26 sec

So I can only bump the timeout based on the factor (seems to be x5 at most) other tests were slower in the failing run.
