Fix missing u32 and LOG_TRACE includes (#7207)

This fixes a compile-error with gcc I was getting from
`LOG_TRACE`(`error: ‘LOG_TRACE’ was not declared in this scope`) and
`u32`(`error: ‘u32’ was not declared in this scope`) being used without
their header-files being included.

Not sure how `romfs_reader.cpp` is even compiling when nothing in its
include-tree is refers to those macros.
