vm: Convert boolean_t to bool

[minsoochoo0122_proton.me]

Test Plan

$ make -j6 TARGET_ARCH=amd64 buildkernel && make -j6 TARGET_ARCH=amd64 buildkernel && make -j6 TARGET_ARCH=aarch64 buildkernel && make -j6 TARGET_ARCH=armv6 buildkernel && make -j6 TARGET_ARCH=armv7 buildkernel && make -j6 TARGET_ARCH=i386 buildkernel && make -j6 TARGET_ARCH=powerpc buildkernel && make -j6 TARGET_ARCH=powerpcspe buildkernel && make -j6 TARGET_ARCH=powerpc64 buildkernel && make -j6 TARGET_ARCH=powerpc64le buildkernel && make -j6 TARGET_ARCH=riscv64 buildkernel

Is there a way to build ALL_TARGETS for buildkernel/buildworld?
