UNREG: don't prefix asm prefixes in via-C mode

commit 64c54fff
("Mark system and internal symbols as private symbols in asm")

Added `internalNamePrefix` helper. Unfortunately it
generates invalid label in unregisterised mode:

$ ./configure --enable-unregisterised
/tmp/ghc19372_0/ghc_4.hc:2831:22: error:
     error: expected identifier or '(' before '.' token
     static const StgWord .Lcl3_info[]__attribute__((aligned(8)))= {

Here asm-style prefix is applied to C symbol.
The fix is simple: apply asm-style labels only to assembly code.
