[flang][cmake] Fix bcc dependencies (#125822)

The Fortran libraries are not part of MLIR, so they should use
target_link_libraries() rather than mlir_target_link_libraries().

This fixes an issue introduced in
https://github.com/llvm/llvm-project/pull/120966.

(cherry picked from commit f9af5c145f40480d46874b643ca2b1237e9fbb2a)
