Subject: [PATCH 1/1] common/filesystem: define ACCESSPERMS if undefined

Normally defined in sys/stat.h on various libc implementations,
but musl libc doesn't seem to have it, leading to this build
issue:

common/filesystem.cpp:86:38: error: 'ACCESSPERMS' was not declared in this scope
   86 |     return (mkdir(dir.toLocal8Bit(), ACCESSPERMS) == 0);

ACCESSPERMS is typically defined as the result of bitwise OR:
S_IRWXU | S_IRWXG | S_IRWXO

This creates the chmod permission 0777, used on the mkdir() call.

ACCESSPERMS is supported on GNU C Library, for compatibility with
BSD libc implementations; the latter also implements ALLPERMS
and DEFFILEMODE, which don't seem to be used by uefitool regardless.

Do not define it on the Windows builds; only do it for the others,
such as Linux.
