[LTP] [PATCH v3 1/2] lapi/fs: Replace loff_t with long long

[Petr Vorel]

loff_t in tst_max_lfs_filesize() would require define _GNU_SOURCE.
Replace with long long to avoid this.

This fixes build error on musl (alpine):

    In file included from unlink09.c:18:
    ../../../../include/lapi/fs.h:58:15: error: unknown type name 'loff_t'
       58 | static inline loff_t tst_max_lfs_filesize(void)

Fixes: 2cf78f47a ("unlink: Add error tests for EPERM and EROFS")
Suggested-by: Jan Stancek <jstancek@redhat.com>
Signed-off-by: Petr Vorel <pvorel@suse.cz>
---
changes v2->v3
* Use just long long instead of define _GNU_SOURCE (Jan)

Later I move this out of LAPI header, but now let's fix the CI.

Kind regards,
Petr
