[gdb/testsuite] structured rename of jit test files

Reorganizes how JIT related test files to be more clear what are related
to JIT reader system tests and what use JIT from ELF objfiles. Those two
approaches are quite different in GDB implementation and require very
different test setup. Keeping distinction clear at the file name level
makes it easier to maintain the testsuite.
