bootloader: move iram_seg 1k up to have better looking idf_monitor output
When 2nd stage bootloader loads the ROM bootloader, it prints a message similar to "entry 0x40080xxx", which idf_monitor decodes (using application ELF file) as one of the reset vectors (xxx is < 400h). This moves the iram_seg of bootloader 1k up to prevent overlap of bootloader .text and application vectors, making the output look nicer. There is still a chance that the entry point decodes as some symbol in application ELF file, but at least it won't have "Exception" in its name.
