build: Use more conservative GResource embedding on non-x86_64
Doing clever things with objcopy is faster and seems to be reliable on
x86_64 Linux, but also doesn't work on all toolchains and architectures:
in particular, Debian has had trouble with this on arm and mips.
In a distro build environment where we are compiling all of GTK every
time, the cost of potentially unreliable builds is higher than the cost
of using slower but more conservative GResource embedding.
