build: add '-z relro -z now' linker flags
These flags could make some sections and the GOT entries of node
process read only to avoid being modified after dynamic linking is
done, thus the security could be enhanced.

# 'force_load' means to include the static libs into the shared lib or
# executable. Therefore, it is enabled when building:
# 1. The executable and it uses static lib (cctest and node)
# 2. The shared lib
# Linker optimizes out functions that are not used. When force_load=true,
# --whole-archive,force_load and /WHOLEARCHIVE are used to include
# all obj files in static libs into the executable or shared lib.
