unix: implement alarm(2) on Linux on all GOARCH except arm* and riscv.

SYS_ALARM is not defined for arm* or riscv, but is available for all other
Linux GOARCH values. Ian suggested I create a new file with build tags
matching these constraints.

In order to handle special case files such as this one (which don't match the
existing syscall_linux_goarch.go scheme), I've added logic to the Linux build
system which can evaluate the build constraints in a given file to determine
whether that file should be appended to the arguments for a given target.
