Correctly link lte-uesoftmodem(-nos1) (hack)

Although not used in the UE, we currently need to link the F1 library into it.
This is because we do not define ASN_DISABLE_OER_SUPPORT (otherwise, F1 has
compilation problems). In this case, some functions are apparently not
correctly defined, giving linker errors in the UE. Linking F1 in solves the
problem.

This is a hack. It would be better to be able to define ASN_DISABLE_OER_SUPPORT
and have no compilation errors or compile everything with
ASN_DISABLE_OER_SUPPORT except F1. I did not do this because I did not find
another way than add target_compile_definitions() to every target except F1
which adds many lines just so that one target (F1 ASN.1) compiles correctly (in
other words, F1 needs to be fixed).
