Do not allow a module exists both in provideLibs and requireLibs

There was an issue that a library installed in the system with stub is
manually marked as requireLibs, so it created link to the self (system)
namespace from linkerconfig. This change checks from conv_linker_config
if there is any common module in provideLibs and requireLibs before
write result to output path.

Bug: 298333253
Test: Build failed when the common module is not removed.
