qemu: update to 8.1.5.

Re-add patch removed in 147fb2841c to avoid
deadlock when when cross compiling to arm musl.
This was noticed in webkit2, with the WebKit2 gir executable causing
qemu-user-static to become stuck.

+Upstream: no
+Reason: errno=EFAULT when the address passed to mremap(2) is not valid
+
+See Rich Felker's comment at https://www.openwall.com/lists/musl/2017/06/21/2 for
+why we need to return errno as described in man mremap(2) from qemu-user-static.
+Also speed up the loop when checking for increasing the mappings size to go
+in steps of TARGET_PAGE_SIZE and OR-in a check for the very last byte of the range.
