[toolchain] Ensure toolchains can build with libslirp support

The Linux userspace platform now has a meaningful all-drivers build
target, which includes the af_packet, slirp, and tap drivers.
Building this target requires libslirp to be available.

Add the libslirp-devel package to the x86 toolchains (which do not use
sysroots), and ensure that all toolchains are capable of building the
all-drivers Linux userspace binary.
