[OE-core] [PATCH 2/2] ovmf: increase path length limit

[Patrick Ohly]

The VfrCompile tool has a hard-coded maximum length for path names
which turned out to be too small by around 20 characters in the
Yocto autobuilder setup. Increasing the maximum by a factor of 4
is relatively easy and makes the problem less likely.
