arch: arm: swap_helper.S: safe guarding GTEXT(z_arm_do_syscall)
z_arm_do_syscall is only defined and used when CONFIG_USERSPACE=y.
Defining the symbol z_arm_do_syscall in assembly without a corresponding
implementation is fine for GNU ld as long as the function is not
actively called, but armlink fails to link in such cases.
Safegaurd GTEXT(z_arm_do_syscall) so the symbol is only referenced when
actively used, that is when CONFIG_USERSPACE=y.
