x86/alternative: Refactor INT3 call emulation selftest

The INT3 call emulation selftest is a bit fragile as it relies on the
compiler not inserting any extra instructions before the
int3_selftest_ip() definition.

Also, the int3_selftest_ip() symbol overlaps with the int3_selftest
symbol(), which can confuse objtool.

Fix those issues by slightly reworking the functionality and moving
int3_selftest_ip() to a separate asm function.  While at it, improve the
naming.
