Fix flash offset on HY_TinySTM103T variant. (stm32duino#1131)

The linker script for the HY_TinySTM103T variant ignored the
LD_FLASH_OFFSET linker flags. This prevented proper operation when using
a bootloader on these boards. The linker script has been replaced with
the generic F103 linkerscript that properly implements this.
