fish, inspector: get rid of COMPILING_VIRT_INSPECTOR

All the define was doing in options.h was masking the declaration of
inspect_mount_root, which was always built-in in inspect.c (because of
the unconditional #define there) anyway.

Since this is common code used by all the C tools, try to avoid extra
knobs which add different code paths for no benefit.
