Due to improved validation of sysctl settings in recent kernels (5.2+, but
also stable kernels like 4.19.53), systemd will log an error message like

    systemd[1]: Failed to bump fs.file-max, ignoring: Invalid argument

during boot. Backport the bugfix from the systemd master.

+Subject: [PATCH] core: set fs.file-max sysctl to LONG_MAX rather than
+ ULONG_MAX
+
+Since kernel 5.2 the kernel thankfully returns proper errors when we
+write a value out of range to the sysctl. Which however breaks writing
+ULONG_MAX to request the maximum value. Hence let's write the new
+maximum value instead, LONG_MAX.
