Updating libefivar & efibootmgr for Android-x86 or BlissOS

[hmtheboy154]

Hi, I am trying to update efivar & efibootmgr repo for BlissOS. Back then we used to use the old fork that is on Android-x86 but now both projects will follow the master branch here. However, on efivar, I've made some changes :

• Because of C99 standard limitation on Android, I have to use sort_r() instead of qsort_r() . Also I replaced secure_getenv() with getenv() in efivarfs.c
• On Android.mk, I updated it based on the updated Makefile, with extra -Wno-typedef-redefinition cflag for makeguids

Here is my fork
https://github.com/android-generic/external_efivar/commits/main

My question is that does switching from secure_getenv() to getenv() affect anything important to libefivar-static or efibootmgr ?
