.github: bump vmactions/solaris-vm from 1.3.9 to 1.4.0

[dependabot]

Bumps vmactions/solaris-vm from 1.3.9 to 1.4.0.

Release notes

Sourced from vmactions/solaris-vm's releases.

v1.4.0

Boot with 2 GB of memory

A job with mem: 2048 could time out at "Starting VM" while the same job vmactions/solaris-vm#63 crashing: its console showed svc.startd: Couldn't fork ... Cannot allocate memory and /tmp: File system full, swap space limit exceeded, and sshd was killed before it ever listened. The cause was in the image, not the runner: svc:/application/man-index rebuilt the man page index with catman on every boot of the snapshot image, peaking at 564 MB for about 50 seconds, on top of a kernel that already takes close to 1 GB at 2 GB. Whether sshd came up first was a race, which is why the failure looked host-dependent.

solaris-builder v2.0.8 ships images with man-index and the other services a CI guest never uses disabled: sstore, the Solaris Web UI (five httpd), the hal/dbus/rmvolmgr removable-media stack, fault notification, the extra virtual terminals, smb, InfiniBand, FCoE, iSCSI, sendmail-client and the compliance guide generator. rad, fmd, auditd and the nfs/autofs pieces stay.

Measured on one host with mem: 2048 and the production CPU flags, ::memstat about a minute after boot:

image	boot-to-ssh	Kernel	User/Anon	Free	daemons RSS
v2.0.7 (as shipped)	timeout	-	-	-	587 MB
v2.0.7, man-index/webui off	26 s	1.45 GB	354 MB	13 MB	~480 MB
v2.0.8	33 s	1.31 GB	252 MB	203 MB	317 MB

The daemons RSS column is the summed resident size of every process after boot; the v2.0.7 figure was taken at 4 GB since that image never reached ssh at 2 GB. 2 GB now boots, but with about 200 MB to spare; give a real build 4 GB or more.

Under the hood

The runtime moves to anyvm v0.6.9 (from v0.6.5). Nothing in that range touches this guest's launch.
