The PTP selftest fails to compile with kernel versions 6.7+ due to
missing header definitions for PTP_MASK_CLEAR_ALL and PTP_MASK_EN_SINGLE.
These definitions were introduced in kernel v6.7 with commit c5a445b.

This fix adds kernel headers to CFLAGS during compilation to ensure
the required definitions are available.

Error before fix:
testptp.c:613:31: error: 'PTP_MASK_CLEAR_ALL' undeclared
testptp.c:615:38: error: 'PTP_MASK_EN_SINGLE' undeclared

Fixes: #878
