[Minios-devel] [UNIKRAFT/MUSL PATCH 15/19] Add stub for ftrylockfile function

[Gaulthier Gain <gaulthier.gain@xxxxxxxxx>]

wip: This commit adds a stub for the ftrylockfile function. This
function needs a stub since it uses the __pthread_self primitive from
musl. It is necessary to re-write this one by considering
pthread-embedded declarations.
