support/testing: TestFileCapabilities: update kernel to 4.19.310

Since the toolchain Bootlin update to 2023.11-1 [1], the arm Linux
kernel build is broken with binutils >= 2.41 with:

  arch/arm/mm/proc-v7.S: Assembler messages:
  arch/arm/mm/proc-v7.S:640: Error: junk at end of line, first unrecognized character is `#'

A similar issue has already be fixed for qemu m68k [2].

Bump to the latest kernel 4.19 that already include the backport
of 790756c7e022 ("ARM: 8933/1: replace Sun/Solaris style flag on section directive")

[1] 7e0e6e3b8618ab942f25b11ee72fbc5a4deefdf1
[2] a1ce9474e40f731f327035d8c0962abb16f00ff7
