[lldb/cmake] unittests: Breakpoint: remove liblldb dep

Remove the liblldb link target for these tests to fix CI failures.

Commit 02572c6 ("[lldb] Enforce that only the LLDB API unit tests
can link liblldb") disallows linking against liblldb for most tests.
Then, Commit f3e2c20 ("Make
SBBreakpoint/SBBreakpointLocation.SetCondition(nullptr) work again") got
merged just after this commit (but before CI could report the
regression).
