fix: test case ut_lind_fs_mmap_unsupported_file

[ChinmayShringi]

Description

Fixes # (issue)

This PR updates the ut_lind_fs_mmap_unsupported_file test to correctly handle the case where an attempt is made to memory map a directory using the mmap_syscall. Directories are unsupported for memory mapping, and the test now checks whether errno is set to ENODEV (No such device) or EACCES (Permission denied) based on system behavior.

Changes:

• Modified the test to assert that mmap_syscall returns -1 on failure.
• Added checks to verify that errno is either ENODEV or EACCES depending on the system’s behavior when attempting to map a directory.

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?
