By Frobenius reciprocity, a representation is induced from the trivial representation of the subgroup $H$ if and only its restriction to $H$ includes the trivial representation. So every non-cyclic abelian group has this property, because an irreducible representation is one-dimensional, so factors through a map to a cyclic group, so has a kernel.

Moreover, this implies that if $H\subset G$ and $H$ has this property, then $G$ does as well, so a sufficient condition is that a group have an abelian subgroup that's not cyclic.

This resolves the case for $GL_n(\mathbb F_p)$, $n>1$ and $p>2$ (the diagonal subgroup), and $n>2$ and $p>3$ p=2$(an abelian subgroup of the$2$-Sylow subgroup). n=2, p=2 is just$S_3$, which manifestly has this property. (Showing that this sufficient condition is not necessary) So$GL_n$for$n>1$has this property.$GL_1$does not, since it is always cyclic. (For cyclic groups, every induced representation fails to be faithful, so take a faithful 1-dimensional irrep.)$A_n$for$n\geq 4$contains the Klein four subgroup of$A_4$and so has this property.$A_3$is cyclic and so does not.
