Subject: [PATCH] Change runtime directory location to follow FHS

Helix allows to specify the location of the runtime directory (which
contains arch-independent modules) via environment variable
`HELIX_RUNTIME`. Using this would require installing a wrapper script
to set this variable prior executing `hx`.

If this environment variable is not set, Helix fallbacks to directory
`./runtime` relative to the directory of the `hx` executable. This is not
suitable for Alpine (FHS).

This patch changes the fallback to `/usr/share/helix/runtime`.
