mozjs60: request stack size on newer musl systems

since 1.1.21 musl supports reading the minimal stack size from the
PT_GNU_STACK elf header[1]. As mozjs tends to build larger stacks and
applications using mozjs aren't RAM friendly anyway we set this header
in the library and prevent patching the applications itself.
