fix(docker): disable glibc _FORTIFY_SOURCE for aarch64-musl cross builds

Browse Source 
When cross-compiling aws-lc-sys for aarch64-unknown-linux-musl using
aarch64-linux-gnu-gcc, glibc's _FORTIFY_SOURCE generates calls to
__memcpy_chk, __fprintf_chk etc. which don't exist in musl, causing
linker errors. Disable it via CFLAGS_aarch64_unknown_linux_musl.
