linux: Add new netlink flags

[jbaublitz]

Description

This change adds some new constants for the DELETE and ACK subset of netlink commands.

Sources

The documentation appears to be out of date, but the header is /usr/include/linux/netlink.h and includes the following:

/* Modifiers to DELETE request */
#define NLM_F_NONREC    0x100   /* Do not delete recursively    */
#define NLM_F_BULK      0x200   /* Delete multiple objects      */
 
/* Flags for ACK message */
#define NLM_F_CAPPED    0x100   /* request was capped */
#define NLM_F_ACK_TLVS  0x200   /* extended ACK TVLs were included */

Checklist

• Relevant tests in libc-test/semver have been updated
• No placeholder or unstable values like *LAST or *MAX are
  included (see #3131)
• Tested locally (cd libc-test && cargo test --target mytarget);
  especially relevant for platforms that may not be checked in CI
