tests: Make the deployment mutable in test-sysroot.js
We attempt to make deployments mutable in the test suite (as opposed to

the tmp files after each test. This is normally accomplished by setting
OSTREE_SYSROOT_DEBUG=mutable-deployments in libtest.sh, but that only
affects the environment variables for that bash instance, not the
process running gjs. So in test-sysroot.js OSTREE_SYSROOT_DEBUG wasn't
set when sysroot.deploy_tree() was called, which means the deployment
was made immutable which eventually causes the test to fail. This only
occurs when the test is run by the root user because for non-root users
_ostree_linuxfs_fd_alter_immutable_flag() would silently fail and the
deployment would be mutable.

specific.
Further, I think in practice forcing tree builders to compute the checksum is an
annoying stumbling block; since we already switched to e.g. computing checksums
always when doing pulls, the cost of doing another checksum for the
kernel/initramfs is tiny. The "bootcsum" becomes more of an internal
implementation detail.
Now, there is a transition; my current thought for this is that rpm-ostree will
change to default to injecting into both `/usr/lib/ostree-boot` and
`/usr/lib/modules`, and stop doing `/boot`, then maybe next year say we drop the
`/usr/lib/ostree-boot` by default.
A twist here is that the default Fedora kernel RPM layout (and what's in
rpm-ostree today) includes a kernel but *not* an initramfs in
`/usr/lib/modules`. If we looked only there, we'd just find the kernel. So we
need to look in both, and then special case this - pick the legacy layout if we
