stat: Nits in stat tests
* Use ourselves as test file instead of /COPYRIGHT, which may or may not
be present in the test environment.
* atf-check understands \n in strings, use it.
* Some file systems don't like creating small holes, so create large ones
instead. This means we need two variables: ps (page size) is the
minimum size of a data region and the alignment for a hole, while hs
(hole size) is the minimum size of the holes we create. This makes no
difference on FreeBSD but makes it easier to port the test to other
platforms.

libgcc_s: export __extendhftf2
We've compiled it since the LLVM 13 import in 2021, but for some reason
never exported it. A user of CheriBSD recently caused Morello LLVM to
emit a reference to it so finish the job and export it.

compat/linprocfs: Fix auxv sbuf leak
linprocfs_doauxv() allocates an automatic sbuf before validating
whether the requested read can be satisfied.
When the computed auxv read length exceeds IOSIZE_MAX, or when the
buffer length is too big, the function returns early without
releasing the sbuf.
Route these early exits through a shared cleanup path so the sbuf is
always deleted after sbuf_new_auto() succeeds.

These tests require SVE hardware support to run so will skip when they

vm_fault: Reset m_needs_zeroing properly
- When allocating a page, we should only consider the PG_ZERO flag when
handling the top-level page.
- Unconditionally reset the flag when restarting the fault handler.
Previously, vm_fault_busy_sleep() would fail to reset it.

imgact_elf: Unconditionally initialize a variable in a note handler
In the sb == NULL case, we are computing the size of the note using a
dummy sbuf drain handler which counts bytes and discards the contents of
the buffer, so the fact that "structsize" is uninitialized doesn't
matter. But, the compiler may complain about this, so we might as well
just initialize it unconditionally to silence the warning, as other
handlers already do.

arm64: Optimise the repeated TLBI workaround
It has been reported that the overhead of repeating all TLBI
instructions is too large [1]. The Software Developer Errata Notices
(SDEN) for the relevant Arm CPUs have been updated so a single
"tlbi vale1is, xzr" followed by "dsb ish" is sufficient to work around
the issues.
Replace the places we repeat TLBI instructions with the new sequence.
