RFR: 8339714: Delete tedious bool type define

[SendaoYan]

Hi all,
  This PR delete tedious bool type define in `src/java.base/unix/native/libjsig/jsig.c` and `src/utils/hsdis/binutils/hsdis-binutils.c`. After JEP 347([JDK-8246032](https://bugs.openjdk.org/browse/JDK-8246032)), I think we can "#include <stdbool.h>" to use bool type directly, like [string.h](https://github.com/openjdk/jdk/blob/master/src/java.desktop/unix/native/libpipewire/include/spa/utils/string.h#L13) do.
  Make code more concision, the risk is quite low.

Additional testing:

- [x] Local build with --with-hsdis=binutils --with-binutils=$HOME/software/binutils
- [ ] Jtreg tests(include tier1/tier2/tier3 etc.) on linux x64
- [ ] Jtreg tests(include tier1/tier2/tier3 etc.) on linux aarch64
