linux-user/alpha: Add define for NR_shmat to enable shmat syscall

For historical reasons, the define for the shmat() syscall on Alpha is NR_osf_shmat; however it has the same semantics as this syscall does on all other architectures, so define TARGET_NR_shmat as well so that QEMU's code for the syscall is enabled. This patch brings our behaviour on the LTP shmat tests into line with that for ARM (still not a perfect pass rate but not "this syscall is completely broken" as we had before). (Problem detected via a clang warning that the do_shmat() function was unused on Alpha.)
