perf beauty: Move uapi/linux/fs.h copy out of the directory used to build perf
It is mostly used only to generate string tables, not to build perf, so move it to the tools/perf/trace/beauty/include/ hierarchy, that is used just for scraping. The only case where it was being used to build was in tools/perf/trace/beauty/sync_file_range.c, because some older systems doesn't have the SYNC_FILE_RANGE_WRITE_AND_WAIT define, just use the system's linux/fs.h header instead, defining it if not available. This is a something that should've have happened, as happened with the linux/socket.h scrapper, do it now as Ian suggested while doing an audit/refactor session in the headers used by perf. No other tools/ living code uses it, just <linux/fs.h> coming from either 'make install_headers' or from the system /usr/include/ directory.

- * Note: for historical reasons, these flags were originally used and

- * using these flags so they wouldn't need to write their own version
- * of chattr/lsattr (which was shipped as part of e2fsprogs). You

- *
- * We have recently hoisted FS_IOC_FSGETXATTR / FS_IOC_FSSETXATTR from
- * XFS to the generic FS level interface. This uses a structure that
- * has padding and hence has more room to grow, so it may be more
- * appropriate for many new use cases.
