Fallback to uname for detecting ARM CPU architecture

Currently running official dart `linux/arm/v7` container image on x86_64 with QEMU results in `Unrecognized ARM CPU architecture`.

This is due to QEMU reporting host `/proc/cpuinfo` instead of the emulated architecture.

Checking `uname` in addition to `/proc/cpuinfo` would make `linux/arm/v7` build work consistently regardless of whether `--use-qemu` is supplied during SDK build time.

TEST=running the qemu bot
TEST=ran the ffi/hardfp_test.dart locally both in AOT and JIT mode.
